Temperature co-efficient of resistance is expressed in terms of___________?
Correct answer: C. ohms/ohm°C
- A. ohms/°C
- B. mhos/ohm°C
- C. ohms/ohm°C
- D. mhos/°C
Explanation
Temperature coefficient is defined as the change in resistance per ohm of original resistance per degree temperature change, α = ΔR/(RΔT). Its unit is therefore ohm per ohm per °C, written as ohms/ohm°C.
