How do you find Thevenin resistance with dependent sources?

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. When using a voltage source, it can be assumed to be 1V for simple calculations.

What is Thevenin equivalent resistance?

The “Thevenin Equivalent Circuit” is the electrical equivalent of B1, R1, R3, and B2 as seen from the two points where our load resistor (R2) connects. In other words, the load resistor (R2) voltage and current should be exactly the same for the same value of load resistance in the two circuits.

Is Thevenin resistance equal to Norton’s resistance?

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.

What is a dependent current source?

In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. An operational amplifier can be described as a voltage source dependent on the differential input voltage between its input terminals.

What do you mean by dependent source and independent source?

An independent voltage source maintains a voltage (fixed or varying with time) which is not affected by any other quantity. They are called dependent voltage (current) sources or controlled voltage (current) sources , and their usual symbols are shown in figure 1.4.

Do current sources have resistance?

The internal resistance of an ideal current source is infinite. An independent current source with zero current is identical to an ideal open circuit. The voltage across an ideal current source is completely determined by the circuit it is connected to.
