A series circuit contains R = 8 Ω, Xʟ = 15 Ω and Xᴄ = 9 Ω and carries an RMS current of 10 A. If the source voltage is written as 10√N V, determine N.

Question

G1 Physics · Accepted Answer

The net reactance is 15 − 9 = 6 Ω. Therefore Z = √(8² + 6²) = 10 Ω and V = IZ = 10 × 10 = 100 V = 10√100 V. Hence N = 100.
