A 100 F capacitor is connected to a 100 ~V , 50 ~Hz AC supply. The rms value of the current is
Options
- A3.14 ~A
- B4.75 ~A
- C2.33 ~A
- D5.5 ~A
Correct answer
A. 3.14 ~A
Step-by-step solution
Given, V_ rms =100 ~V , f=50 ~Hz C₁=100 F =100 10⁻⁶ ~F Now, reactance of capacitor, X_C= 1 C = 1 C 2 f X_C= 1 100 10⁻⁶ 2 50 = 100 r. m. s value of current in circuit will be I_ rms = V_ rms X_C = 100 100 = A =3.14 ~A
