The resistances of a wire at temperatures 1°C and 0°C are related by:
Correct answer: A. R1 = R0(1 +αt)
- A. R1 = R0(1 +αt)
- B. R1 = R0 (1-αt)
- C. R1=R02(l+αt)
- D. R1=R02(1-αt)
Explanation
.Rt = Ro(1 + α∆T) is the formula for the relationship between resistance and temperature. These are some of the most prevalent resistance-to- temperature relationships. The resistance of both the conductors increases as the temperature of such conductors rises.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
