Question

in a series LCR circuit which is connected to an AC voltage source choose the incorrect statementthe equation of an alternating voltage is V = 220 Sin Omega T + 5 by 6 and the equation for current is I=10sin(omega t +π\6)
the impedence of the circuit​

Answer 1

Answer:

We know that , Z=
