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?

1 A space tether is a long string or a wire that connects two objects that are in orbit together An orbiting tether tends to straighten out along a radial line because the force of gravity varies slightly along its length The pull of gravity is stronger nearest the Earth and weakest furthest away That means there is a net force on a tether which stretches it and keeps the line See Answer
