Question

1. Shown below is a simple potential divider circuit. Determine Vab and Vbc in terms of R1, R2, and Vin. What is the phase relationship between Vab and Vin? What is the phase relationship between Vbc and Vin?

2. The series RC circuit is often referred to as a frequency dependent potential divider circuit. Determine Vab and Vbc in terms of R1, C, and Vin and the source frequency f, given that Vin = Vsin(2ft). What is the phase relationship between Vab and Vin? What is the phase relationship between Vbc and Vin?

THANKS!

Explanation / Answer

Hi, If an AC circuit consist of just omic resistance (R), in that case no phase difference btw Vin and Vab or Vba, for second figure: AC circuit contains capacitor therefor voltsge Vbc will be bhind of Vin voltage, Vin = Vsin(2pft-theta), where theta is phase angle
