What are dependent voltage sources?

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.

CAN YOU DO source transformation with dependent sources?

Yes, we can apply source transformation to dependant sources. Analysis of the circuit remains same as that of independent sources. While source transformation, dependent current source will be converted to dependent voltage source and vice versa.

How do you solve a dependent source in a circuit?

Analyze Circuits with Dependent Sources

  1. The first step is to label the nodes.
  2. Rearranging gives you the node voltage equation:
  3. At Node B, again apply KCL and plug in the current expressions from Ohm’s law:
  4. Rearranging the preceding equation gives you the following node voltage equation at Node B:

How do you find node voltage?

Node Voltage Method summary

  1. Assign a reference node (ground).
  2. Assign node voltage names to the remaining nodes.
  3. Solve the easy nodes first, the ones with a voltage source connected to the reference node.
  4. Write Kirchhoff’s Current Law for each node.
  5. Solve the resulting system of equations for all node voltages.

Can you add dependent and independent voltage sources?

You need to make sure the dependent source is a function of the independent source. The independent current source is and the dependent current source gvx point in the same direction, so you can add these two current sources to get the total current ieq going through the resistor combination R1 and R2.

What are dependent and independent sources in electric circuits?

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.
