1
Increases heat production
2
Decreases heat production
3
Has no effect
4
Only affects light output
Answer and Solution
Answer
A. Increases heat production
Solution:
According to Joule's law, as resistance increases in a circuit with constant current, the heat produced increases, since H is proportional to R when other factors are constant.
