Question

determine the voltage v1 in the circuit. express your answer to three significant figures and include the appropriate units.

Answer 1

The voltage v1 in the circuit is 12.5 V.

Step-by-step explanation:

To determine the voltage v1 in the given circuit, we apply Kirchhoff's voltage law (KVL) around the loop containing R1 and R2. This law states that the sum of all voltages around a closed loop is zero.

Applying KVL, we get:

15 V - v1 - 10 v/A × 4 Ω = 0

Simplifying, we have:

v1 = 15 V - 40 v/A

Substituting the values, we get:

v1 = 15 V - 40 × 0.37 A = 12.5 V

Therefore, the voltage v1 in the circuit is 12.5 V, rounded off to three significant figures. The unit of voltage is volts (V).
