(a) What is the resistance of a nichrome wire at 0°C if its resistance is 100? at 11.5°C? (b) What is the resistance of a carbon rod at 25.8°C if its temperature coefficient of resistance is 0.0160/°C at 0°C?
Added by Jack S.
Step 1
Given that the resistance of the nichrome wire at 0°C is 100Ω, the resistance at 11.5°C can be calculated as follows: R11.5 = 100 * (1 + α * 11.5) However, without the value of α for nichrome, we cannot calculate the exact resistance. (b) For the carbon rod, Show more…
