An alternating e.m.f. given by e=200 sin 50 t is applied to a circuit containing only a resistance of `50 Omega`. What is the value of r.m.s. current in the circuit?

A

0.02828 A

B

0.2828 A

C

2.828 A

D

28.28 A

Text Solution

Verified by Experts

The correct Answer is:
C
`I_(rms)=(e_(rms))/(R)=(e_(0))/(sqrt(2)R)=(200x0.707)/(50)`
`I_(rms)=2.828A`
