50 F capacitor is connected to a 250 ~V , 50 ~Hz AC supply. Then the rms current of the circuit is
Options
- A1.25 ~A
- B4.9 ~A
- C5 ~A
- D6 ~A
Correct answer
A. 1.25 ~A
Step-by-step solution
Given, C= 50 F = 50 10⁻⁶ ~F Source voltage, aligned & V=250 ~V & f=50 ~Hz aligned Capacitive reactance, aligned & X_C= 1 2 f C = 1 2 50 50 10⁻⁶ =200 & I_ rms = V_ mms X_C = 250 200 =1.25 ~A aligned
