Quick Answer: What Is Meant By Dependent Sources?

Can you do a source transformation with dependent sources?

Source transformation is applicable even for the circuits which have dependent sources.

Let’s consider the circuit shown in Figure 7(a)..

How do you find Thevenin resistance?

Find the Thevenin resistance by removing all power sources in the original circuit (voltage sources shorted and current sources open) and calculating total resistance between the open connection points. Draw the Thevenin equivalent circuit, with the Thevenin voltage source in series with the Thevenin resistance.

Which method is best for voltage sources?

Which method is best for voltage sources? Explanation: Every voltage source connected to the reference node reduces the equations to be solved. Thus, the node-voltage method is best for voltage sources.

Why do we use source transformation?

Source transformation methods are used for circuit simplification to modify the complex circuits by transforming independent current sources into independent voltage sources and vice-versa. … This source transformation method can also be used to convert a circuit from Thevinin’s equivalent into Norton’s equivalent.

What is source transformation theorem?

Source transformation is the process of simplifying a circuit solution, especially with mixed sources, by transforming voltage sources into current sources, and vice versa, using Thévenin’s theorem and Norton’s theorem respectively.

What is a dependent sources in circuits?

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.

How do you calculate current source?

The simplest non-ideal current source consists of a voltage source in series with a resistor. The amount of current available from such a source is given by the ratio of the voltage across the voltage source to the resistance of the resistor (Ohm’s law; I = V/R).
