You have a 220 Ohm resistor and a 0.700 H inductor.  Suppose you take the resistor and inductor and make a series circuit with with a voltage source that has a voltage amplitude of 25.0 V and an angular frequency of 210 rad/s.  What is the impedance of the circuit?  What is the current amplitude?  What is the voltage amplitude across the resistor?  What is the voltage amplitude across the inductor?  What is the phase angle phi of the source voltage with respect to the current?  Does the source voltage lag or lead the current?
