Question

(TCO4) Solve for the unknown currents and unknown voltages using the information provided in the figure below. (Hint: Use KVL, KCL, Ohm's law, Watt's law, the current divider rule, or the voltage divider rule.) Assume Ps1= 1.2W, Pr2= 200 mW, Vs1= 30V, and R1= 250Ohm. Calculate I1, I2, I3, Vr1, and VR3.

Explanation / Answer

PS1=1.2 WATTS

1.2=VS1*I1

I1=1.2/30=0.04 AMPS

VR1=I1*R1=0.04*250=10 VOLTS

VR3=VR2=VS1-VR1=30-10=20 VOLTS

PR2=200*10^-3=VR2*I2

I2=(200*10^-3)/20=0.01 AMPS

I3=0.04-0.01=0.03 AMPS
