A 30μ F30 \mu \mathrm {~F}capacitor is connected to a 150 V, 60 Hz ac supply. The rms value of current in the circuit is

A

17 A

B

1.7 A

C

1.7 mA

D

2.7 A

Answer

1.7 A

Explanation

Solution

: Here, , C=30μ F=30×10−6 F\mathrm { C } = 30 \mu \mathrm {~F} = 30 \times 10 ^ { - 6 } \mathrm {~F}

Capacitive reactance ,
