An inductor of 1 H and negligible resistance is used on 220 V a.c. mains of frequency 50 Hz. Calculate the effective current.

Text Solution

Verified by Experts

Here, `L = 1 H, E_(v) = 220 V, v = 50 Hz`
`I_(v) = (E_(v))/(X_(L)) = (E_(v))/(omega L) = (E_(v))/((2 pi v) L) = (220)/(2 xx 3.14 xx 50 xx 1) = 07 A`
