Your response differs from the correct answer by more than 10%. Double check your calculations. (b) rms current Incorrect: Your answer is incorrect. . Your response differs from the correct answer by more than 100%. A (c) maximum current in the circuit Incorrect: Your answer is incorrect. . Your response differs from the correct answer by more than 100%. A

Explanation / Answer

given

Vrms = 6 v

f = 60 hz

C = 7 micro F

a) capacitive reactance, Xc = 1/(2*pi*f*C)

= 1/(2*pi*60*7*10^-6)

= 378.9 ohms

b) Irms = Vrms/Xc

= 6/378.9

= 0.0158 A

c) Imax = sqrt(2)*Irms

= sqrt(2)*0.0158

= 0.0224 A
