# 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

Vb = r * Ia

where r is the gain of the dependent source. Notice that the units of r are V/A. The current Ia, in Amps, and voltage Vb, in Volts, are measured using the ammeter and voltmeter. Thus the gain of the dependent source can be determined from the meter readings.

### Challenges:

1. Set the gain of the CCVS equal to 4 V/A to check the answer to problem P2.7-1.

2. 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.

3. Determine the gain of the CCVS required to cause Ia = 8 A. Verify that the meter readings are consistent with the gain of the dependent source.
