Solution: a) What would have to be the self-inductance of a solenoid for it to store 11.0 J of energy when a 1.50A current runs through it?
b) If such an inductor is connected to a capacitor of 50 uF, what will be the resonance frequency in rad/s? and in Hz?

a) What would have to be the self-inductance of a solenoid for it to store 11.0 J of energy when a 1.50A current runs through it?

b) If such an inductor is connected to a capacitor of 50 *uF*, what will be the resonance frequency in rad/s? and in Hz?
