## What happens to dependent sources in Thevenin?

Dependent Sources and Thevenin’s Theorem Thevenin’s theorem can be applied when analyzing a circuit with dependent sources. In this case, all independent sources are turned off and the RTh is calculated by applying a current source or voltage source at the open terminal.

## How do you identify a dependent source in a circuit?

A dependent source is a current or voltage source whose value is not fixed (i.e., independent) but rather which depends on some other circuit current or voltage. The general form for the value of a dependent source is Y=kX where X and Y are currents and/or voltages and k is the proportionality factor.

How do you find Thevenin equivalent circuit?

The process for analyzing a DC circuit using Thevenin’s Theorem requires the following steps:

1. Find the Thevenin Resistance by removing all voltage sources and load resistor.
2. Find the Thevenin Voltage by plugging in the voltages.
3. Use the Thevenin Resistance and Voltage to find the current flowing through the load.

### Where can I find Thevenin and Norton?

Thevenin voltage is equal to Norton’s current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.

### What are independent and dependent sources?

Independent source are those, whose value of either the voltage or the current to be delivered is independent of any other parameter of the network. Where as the dependent sources are those, whose value of either the voltage or the current to be delivered is dependent or controlled on other parameters of the network.

What are the conditions to apply the Thevenin’s theorem?

Thevenin’s theorem can be applied to both AC and DC circuits. But it should be noted that this method can only be applied to AC circuits consisting of linear elements like resistors, inductors, capacitors.

## How can Thevenin’s resistance and Norton resistance be correlated in an AC circuit?

Thevenin and Norton’s resistances are equal. Thevenin voltage is equal to Norton’s current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.
