Question

An electric heater produce more heat than an electric bulb when they are connected in parallel. which of the two has the smaller resistance
​

Answer 1

Explanation:

The electric heater has smaller resistance.

Heat produced, H= V^2* t /R

⟹H∝ 1/R

R

R Electric heater produces more heat. Hence it has less resistance.

produces more heat. Hence it has less resistance.Bulb produces less heat and therefore it has greater resistance.
