Question

A solenoid with inductance L = 2.0 H is connected in series with a resistor R = 10 ohms, as well as an AC power supply that is providing current I(t) = I₀ * cos( 2π * f * t ). The current has an amplitude of 2 A and a frequency of 60 Hz.

a) Draw a diagram of the circuit.

b) At time t = 0 seconds, what is the change in voltage across both the inductor and the resistor?

c) Find the average thermal power dissipation in both the inductor and resistor.

d) What kind of capacitor do you need to cause the phase between the voltage difference across the supply and the current to be 0, if you are connecting it in series with the inductor and resistor?

I don't know what to tell you, this is word for word how it was given to me. What seems to be missing/incorrect? Is there an equation that needs to be derived from another? (I would've replied directly, but it looks like this website will not allow me to for some reason.)
