Solved Step by Step with Explanation- Circuit Analysis: V, I, P

Answers

I_total = V / R_total

I_total = 20V / 90Ω ≈ 0.2222 A

V2 = 0.2222 A * 10Ω = 2.222 V

V3 = I_total * R3

P = I^2 * R

P1 = I1^2 * R1

P3 = (0.2222 A)^2 * 30Ω ≈ 0.148 W

So, in summary, the voltage, current, and power for each resistor in the circuit are as follows:

Total Power = P1 + P2 + P3 ≈ 2.469 W + 0.0491 W + 0.148 W ≈ 2.6661 W
