1. A generator has a 150-turn square coil, 5cm on a side.
Part A. Find the peak emf in this coil when it's rotating at 110Hz in Earth's field, B=5A????110?5T .
Part B. Find the peak emf in this coil when it's rotating at 110Hz in a strong 6.2T field.
2. A home receives 1.7kW of electric power from a transformer on a nearby pole. The line from the substation to the transformer is at 12kV and has 0.14? resistance.
Part A. What fraction of the power is lost in this transmission line?
3. A 240-turn coil carries 310mA.
Part A. If the magnetic flux through the coil due to this current is 0.85Wb , what's the coil's inductance?
4. Find the inductance required to store 1.1J of energy with current of 9.0A through the inductor.
5. You have a variable capacitor ranging from 6.0pF to 8.7pF .
Part A. What inductor should be used with this capacitor in an FM radio receiver covering the entire FM band, 94MHz to 113MHz ?
Express your answer to two significant figures and include the appropriate units.
