          PRACTICE PROBLEM 2A2

Find V1 and V2 in the circuit shown in Fig: 2.43. Also, calculate i1 and i2 and the power dissipated in the 20-Ω and 40-Ω resistors.

Answer: V1 = 10 V, V2 = 5 V, i1 = 416.7 mA, i2 = 250 mA, power dissipated in the 20-Ω resistor = 2.083 W, power dissipated in the 40-Ω resistor = 2 W.

Step 1

We can use the voltage divider rule to find V1: V1 = (R2 / (R1 + R2)) * Vin In this case, Vin is 15V, R1 is 10Ω, and R2 is 20Ω. Plugging in these values, we get: V1 = (20Ω / (10Ω + 20Ω)) * 15V V1 = (20Ω / 30Ω) * 15V V1 = (2/3) * 15V V1 = 10V Show more…
