Using an ac voltmeter, the potential difference in the electrical line in a house is read to be 234 V. If the line freqency is known to be 50 cycles per second, the equation for the line voltage is

A

165 sin `(200pit)`

B

234 sin `(100pit)`

C

331 sin `(100pit)`

D

440 sin `(200pit)`

Text Solution

Verified by Experts

The correct Answer is:
C

Peak voltage, `V_(0) = sqrt(2)V_(rms) = 331V`
`omega=2pif=100pi`
`rArr V_(L) = 331sin(100pit)`
Where, `V_(L)` is line voltage.
