1) A 1.5H inductor has a constant current of 2.5A.
a) find the energy that it holds
b) what is its voltage?
c) what is its energy after its current drops to zero and stays zero?
2) What is the Vm value (amplitude) of a 240 Vrms 60Hz sinusoid? What power is dissipated when a 20 olhm resistor is connected to it?
