A high tension (HT) supply of, say, 6 kV must have a very large internal resistance. Why?
An astronaut uses a small motor, rated at 93% efficient, that is connected to a 12-volt [V] power supply on Mars. The motor has a resistance rating of 2.3 kiloohms [kΩ]. How long will it take to produce 3.4 calories [cal] of energy in units of minutes [min]?
What resistance, R, should be placed in series with the galvanometer, G, if it is to show a full deflection when the potential across the resistor is 6 V. The maximum current through the galvanometer is 250 mA and its internal resistance is 3 Ω.
(a) 24 Ω
(b) 23 Ω
(c) 3 Ω
(d) 5.25 Ω
(e) 21
