1. NASA tested a power generation system that involvesconnecting a small satellite to the space shuttle with a conductivewire several kilometers long. Explain how such a system cangenerate electricity.
2. The use of high-voltage lines in homes (for example, 600 V or1,200 V) would reduce energy waste. Why are they not used?
3. What parameters affect the inductance of a coil? Does theinductance of a coil depend on the current in it?
4. How does resistance, capacitive reactance and inductivereactance change, when the frequency in a circuit isincreased?
5. Does the phase angle depend on the frequency? What is the phaseangle when the inductive reactance is equal to the capacitivereactance?
