An electric generator consists of a rectangular coil of wire rotating about its longitudinal axis which is perpendicular to a magnetic field, the strength of which, B. can be adjusted. The coil has 158 turns of wire and measures 18.00 cm by 26.00 cm. The ends of the wire are connected to an external circuit a) If it is desired that the generator provides an emf with an ms value of 230V oscillating at 50 Hz, what should be the strength of the magnetic field? b) If the extenal circuit connected to this generator consists of a 0.2 H inductor, a 36 µF capacitor and a 220 2 resistor connected in series, what is the impedance of this circuit? c) What is the peak current through the resistor? d) What is the average power dissipated in the circuit? c) What is the peak voltage across the inductor? 0 What is the peak voltage across the capacitor? g) The generator frequency is now changed so that the circuit is now in resonance. What is that new (resonance) frequency?
