If V=100sin (100t)V and I =100sin `(100t+(pi)/(3))` mA are the instantaneous values of voltage and current, then the rms values of voltage and current are respectively

A

70.7V, 70.7mA

B

70.7V, 70.7A

C

141.4V, 141.4mA

D

141.4V, 141.4A

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(rms) = (V_(0))/(sqrt(2)) = (100)/(sqrt(2)) = 70.7V`
`I_(rms) = (I_(0))/(sqrt(2)) = (100)/(sqrt(2) = 70.7m A `
