Question

A 100 V RMS source is connected across an ideal inductor with Xʟ = 20 Ω and an ideal capacitor with Xᴄ = 25 Ω in parallel. Determine the magnitude and nature of the source current.

G1 Physics · Accepted Answer

Iʟ=100/20=5 A lagging and Iᴄ=100/25=4 A leading. Their difference is 1 A lagging, which is the source current.
