Question

In a two element series circuit, the applied voltage and the resulting current are v(t) = 60 + 66 sin (1000t) V, i(t) = 2.3sin (1000t + 68.3) 3 A. The nature of the elements would be

(a) R  C

(b) L  C

(c) R  L

(d) R  R

I had been asked this question in homework.

This intriguing question comes from Sinusoidal Steady State Analysis topic in portion Signals and Amplifiers of Electronic Devices & Circuits

Answer 1

Right option is (a) R  C

To explain I would say: RC circuit causes a positive shift in the circuit.
