A  circuit element has the following voltage across it and current running through it. ?(?) = 3 cos(100? + 30°) V, ?(?) = 50sin(100? + 30°) mA. Assume polarities are chosen so that the current is flowing into the positive voltage terminal. (a) Determine if this circuit element is a resistor, capacitor, or inductor. (b) Find the impedance of this circuit element. (c) Find the component value of the circuit element. ie. if it is an resistor find R, if it is a capacitor, find C, if it is an inductor, find L.
