Voltage and Alternating Current

1-) 1. The voltage = 30(200 + 30°) is across an inductor of inductive reactance L= 62 Ω. Find the expression for the current in the inductor. Draw the phasor diagram of and .
A: () = 0.484(200 − 60°) .

2-) The voltage v = 17sin(20πt + 30°) V is over a capacitive reactance capacitor Xc = −45 Ω. Find the expression for the current in the capacitor.
Draw the phasor diagram of v and i.
A: i(t) = 0.378sin(20πt + 120°) A.
