A 44 mH inductor is connected to 220 V, 50 Hz ac supply. Determine the rms value of current in the circuit.

Text Solution

Verified by Experts

Given inductance
`L = 44mH=44xx10^(-3)H`
`V_("rms")=220V`
Frequency of Inductor f = 50 Hz ltbRgt Inductive resistance `X_(L)=2pi fL`
`=2xx3.14xx50xx44xx10^(-3)`
`13.83 Omega`
The rms value of current in the circuit
`I_("rms")=(V_("rms"))/(X_(L))=(220)/(13.83)15.9A`
