Question

an inductive circuit contains resistance of 10 ohm and an inductance of 20 H. if an AC voltage of 120 V and frequency 60 hertz is applied to the circuit, the current would be nearly
a)0.32 A
b)0.016 A
c)0.48 A
d)0.80 A

I will mark you as brainliest if you give me explanation...

Answer 1

Note that the aggregate impedence when given of this circuit is:

ZT=R+JωL(Ω) The above is the intricate number which speaks to the impedence.

Anyway since we are just given the impedence edge we can utilize that to discover the estimation of the inductance.

The rakish speed is given by: ω=2⋅π⋅f ZT∠θ→R2+(ωL)2 −−−−−−−−−√∠arctan(ωLR) Arctan (ωLR) = 45 arctan (2⋅π⋅1000L100)=45.
