Explanation:
see your question is wrong, actually resistence is affected by heat not what is affected by resistence. but if the resistence in a circuit is doubled then the voltage will be low as compared to the before voltage. hope it will help you.

Answer:
Heating of an electrical circuit is equal to the energy dissipated. Energy is power multiplied by time, therefore the rate of heating is equal to the power measured in the circuit. Power is equal to the square of the electrical current, multiplied by resistance. Therefore power is directly proportional to the resistance, for a given current flow. If resistance is doubled, and current remains the same, the power will double and thus the rate of heat will double
