14. The temperature co-efficient of resistance of a wire at 0^° C is 0.00125 ^° C-1. At 25^° C its resistance is one ohm. The resistance of the wire will be 1.2 ohm at (1) 225 K (2) 190^° C (3) 260^° C (4) 185 K
The temperature coefficient of resistance of a wire is 0.00125 per °C. At 300 K, its resistance is 1 ohm. This resistance of the wire will be 2 ohm at (IIT-JEE 1980)
