Given the circuit shown below, answer the questions which follow: VR2_RMS VR4_pk PR3

Solution

SERIES CIRCUIT CURRENT PASSING THROUGH ALL RESITOR IS

I=(16)/(1+2+3+4)K OHM)

1.6mA

VR2=(R2*I)=(2KOHM*1.6mA)=3.2 Vrms

VR4pk=(R4*I)*SQRT(2)=(4*1.6*1.414)=9.05 Vpk

PR3=(I^2)(R3)=((1.6mA)^2)*3KOHM=7.68mWATT
