Expert Solution
Step 1

Given circuit,

Electrical Engineering homework question answer, step 1, image 1

Step 2

Now,

Voltage vst=35sin4000t,

here,

V=35∠0°ω=4000 rad/s

Calculating the values of reactances,

Inductive reactance,

 XL=ωL=4000×2.5×10-3=10 Ω

Capacitive reactance,

XC=1ωC=14000×12.5×10-6=20 Ω

Step 3

Now,

Drawing the equivalent circuit in phasor form,

Electrical Engineering homework question answer, step 3, image 1

here,

20 Ω∥-j20 Ω

Thus the equivalent resistance is,

Req=20×-j2020×-j20=10-j10 Ω

steps
