Superconductor at very low temperature(≈0K) has _____ resistance and at room temperature(≈300K) has _____ resistance
The winding of a motor has a resistance of 80 ohms at 150C. Find its resistance at 500 C. the temperature co-efficient of resistance is 0.004/0C
The resistance of a coil of aluminum wire at 180C is 200 ohm. The temperature of the wire is increased and the resistance rises to 240 ohm. If the temperature coefficient of resistance of aluminum is 0.0039/0Cat 180C, determine the temperature to which the coil has risen.
