# Current Controlled Voltage Source (CCVS)

Here is a circuit that contains a Current Controlled Voltage Source (CCVS). The gain of the CCVS can be changed using the scrollbar.

When the gain of the CCVS is equal to 4 V/A this is the circuit considered in problem P2.7-1 of
**Introduction to Electric Circuits, 7e** by R.C. Dorf and J.A. Svoboda. In problem P2.7-1 the gain of the CCVS is denoted by the symbol r. Then

V_{b} = r * I_{a}
where r is the gain of the dependent source. Notice that the units of r are V/A. The current I_{a}, in Amps, and voltage V_{b}, in Volts, are measured using the ammeter and voltmeter. Thus the gain of the dependent source can be determined from the meter readings.

### Challenges:

- Set the gain of the CCVS equal to 4 V/A to check the answer to problem P2.7-1.
- Set the gain of the CCVS equal to 8 V/A. Verify that the meter readings are consistent with the gain of the dependent source.
- Determine the gain of the CCVS required to cause I
_{a} = 8 A. Verify that the meter readings are consistent with the gain of the dependent source.
