Why do we prefer parallel combination in domestic circuits 3 reasons?

(i) If one electrical appliance stops working due to some defect then all other appliances keep working properly. (ii) Each electrical appliance has its own switch due to which it can be turned on or turned off independently without affecting other appliances.

Why is the series arrangement not used for domestic?

In series circuits voltage is divided. Each component of a series circuit receives a small voltage so the amount of current decreases and the device becomes hot and does not work properly. Hence the series arrangement is not used in domestic circuits.

What is an example of a parallel circuit in your home?

An example of a parallel circuit is the wiring system of a house. A single electric power source supplies all the lights and appliances with the same voltage. If one of the lights burns out current can still flow through the rest of the lights and appliances.

What are the advantages and disadvantages of series and parallel connections in homes?

Complete answer:
Advantages Disadvantages
If there is a fault in one of the electric appliances the current is able to pass through different paths of the circuit. In parallel circuits we cannot increase the voltage since the resistance decreases in the parallel circuit.

Are Christmas lights a parallel circuit?

The path of the electric current flows through the circuit from the source and back around a single wire. The lights provide a resistance when a voltage is applied which passes current to each light bulb. … Christmas lights arranged in a parallel circuit. Each light has its own wire to the source.

Why all home appliances are connected in parallel list two advantages?

Two advantages

(i) To have equal potential difference across each appliance. (ii) Each appliance has separate switch to the flow of current through it so that each circuit can work independently.

Why don’t we use series combination in electric appliances?

Answer : The current is same throughout the circuit in series combination. So we cannot connect various electrical appliances as they draw different amount of current to operate. Secondly if one appliance connect in a series circuit fails other appliances will also not work as circuit will break.

When would you use a series circuit?

Automatic house- heating equipment has a thermostat and safety cut-out connected in series with a voltage source. Water heaters well water pump lamps freezers and refrigerators are some of the other appliances which use a series circuit.

Why is tungsten used almost exclusively?

The metal tungsten is almost exclusively used for the filament of the electric lamp because it has a very high melting point due to which it does not melt even when it is heated to high temperatures due to the passage of electric current.

What circuit is used in homes?

parallel circuits

Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets switches and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.

What happens if a bulb is removed from a parallel circuit?

If one of the bulbs of a parallel circuit is removed the remaining bulb (s) continues to be lit as the terminal voltage is unaffected. If observed precisely there will be slightly voltage improvement may or may not be noticeable depending on the wattage of the bulb removed .

Is Street Lights series or parallel?

Street lights are always connected in parallel because if it was in series then due to fault in any of the bulb the whole line will be switched off then and till the fault is not cleared it’ll be dark. But if they are connected in parallel then even if there is fault in one bulb won’t affect the whole line.

Is it better to wire a house using a series circuit or a parallel circuit?

Explanation: As mentioned above parallel circuits are the most well known in homes and office buildings. … The light above you is powered by a parallel circuit that is also wired in series through the light switch on the wall. Without the series leg of the circuit you could not control the light in the room.

What are the advantages of having a parallel connection for the appliances at home Brainly?


Why should we connect electric appliances in parallel in a household circuit What happens if they are connected in series?

1. The electric appliances are connected in parallel in a household circuit. Because in parallel wiring if any electric appliance is switched off other appliances don’t get off. … If one appliance in a set of series combination breaks down the circuit becomes open and the flow of current ceases.

What are the disadvantages of parallel connection at home?

parallel connection:
  • It requires the use of lot of wires.
  • We cannot increase or multiply the voltage in a parallel circuit.
  • Parallel connection fails at the time when it is required to pass exactly same amount of current through the units.

What is Ohm’s law state?

Ohm’s law states that the current through a conductor is proportional to the voltage across the conductor. … V=IR where V is the voltage across the conductor and I is the current flowing through it.

What is the need of combining different resistors What is the resultant resistance when a number of resistances are connected in series?

According to law of combination of series the combined resistance of any number of resistances connected in series is equal to the sum of the individual resistances.

What do you understand by mixed combination of resistance?

mixed combination of resistance means when two or more than two resistors are connected in series and parralel simultaneously.

Why do we use series and parallel circuits?

In a series circuit every device must function for the circuit to be complete. If one bulb burns out in a series circuit the entire circuit is broken. In parallel circuits each light bulb has its own circuit so all but one light could be burned out and the last one will still function.

Why are series and parallel circuits important?

Series circuit connection gives us the opportunity to connect more than two loads to a common switch. Street lights are a very good example of this. Parallel circuit connection makes it possible for us to connect loads to their individual switch.

Why would an electrician use a series circuit?

A series circuit provides exactly one path between any two points for electric current. These circuits have the advantage of making each component very dependent on the other components. This means that if one component is removed all of the components turn off.

Why do we use tungsten as bulb filament instead of copper or aluminium?

The melting point and resistivity of Tungsten are very high. At high temperatures it does not burn quite well. … Hence tungsten is mainly used as the heating element of electric bulbs.

Why is an electric bulb filled with argon and nitrogen gas?

The filament in an electric bulb is made using tungsten which would burn quickly when it comes in contact with the oxygen in the air. … Hence bulbs are filled with chemically inactive Nitrogen or Argon gas in order to prevent the oxidation of tungsten filament used in the bulb.

Why are copper and aluminium wires used?

Copper and aluminium are most frequently used as the electrical conductors in electrical cables due to their low resistance and excellent conductivity. These metals are both ductile and relatively resistant to corrosion so they can be easily shaped into wires and they so not degrade over time.

When would you use a parallel circuit?

A parallel circuit has one function: to keep the electricity flowing when one pathway is interrupted. A prime example is light fixtures that use multiple light bulbs. When a single bulb in the fixture goes the light fixture continues to operate.
