A `220 V, 50 Hz AC` supply is connected across a resistor of `50 k omega`. The current at time `t` second. Assuming that it is zero at `t = 0`, is

A

`4.4 sin (314 t) m A`

B

`6.2 sin (314 t) mA`

C

`4.4 sin (157 t) mA`

D

`6.2 sin (157 t) mA`

Text Solution

Verified by Experts

The correct Answer is:
2
`i = i_(0) sin omega t`
`omega = 2 pi f , i_(0) = (E_(0))/(R ) = (sqrt(2) xx E_("rms"))/(R )`
