## Why is equivalent circuit diagram important?

The equivalent circuit diagram of any device can be quite helpful in the pre-determination of the behavior of the device under the various condition of operation. It is simply the circuit representation of the equation describing the performance of the device.

## What is the equivalent resistance of the circuit?

The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network.

## What is the formula of equivalent current?

The current in the current source branch is 0.1 cos(2π10t) and the current in each of the other three branches is equal to the voltage VA divided by the impedance of the branch i.e. I(ω)=VA(ω)/ZBranch.

## What is the method of equivalent current is used for?

Equivalent currents provide valuable information about the ionospheric electrodynamics and thus they can be used for example in studies of space weather ionosphere-magnetosphere coupling and the magnetotelluric source effect. We derive equivalent currents by using the spherical elementary current system method.

## What is the equivalent circuit of a quartz crystal?

series RLC circuit
The equivalent electrical circuit for the quartz crystal shows a series RLC circuit which represents the mechanical vibrations of the crystal in parallel with a capacitance Cp which represents the electrical connections to the crystal. Quartz crystal oscillators tend to operate towards their “series resonance”.

## What is diode equivalent circuit?

Diode equivalent circuit: An equivalent circuit is a combination of elements properly chosen to best represent the actual terminal characteristics of a device or system in a particular operating region. There are three models of diode which are piecewise linear simplified and ideal model.

## What does Thevenin’s equivalent circuit consists of?

The equivalent circuit consists of a constant voltage source and a single series resistor called the Thevenin voltage and Thevenin resistance respectively. Once the values of the equivalent circuit have been calculated subsequent analysis of the circuit becomes much easier.

## Why is equivalent resistance important?

The equivalent resistance is where the total resistance connected either in parallel or in series. Electrical resistance shows that how much energy will be required when we move the charges i.e. current through the circuit. If we need lots of energy then the resistance necessary should also be high.
