16) A coil has an inductance of 3 Henry’s, what will be the voltage drop across it if the frequency is 60 HZ and current is 4 amps?

Answer 1

Find the inductive reactance X_l using the formula X_l =2pifL where f=60 hz and L=3H use the voltage relationship V= IX_l and plug in the values to get V= 4(2pi 60)3. So V=12(120pi) =4523.893 volts. V=4.523kV.
