Question

State whether an electric heater will consume more electrical energy per second when the length of its heating element is reduced . give reason​

Answer 1

Answer:

• The electric heater will consume more electrical energy when the length of its heating element is reduced because resistance is directly proportional to length ((R=ρlA) ( R = ρ l A ) ). Hence, resistance will decrease. Power is inversely proportional to resistance (P=V2R) ( P = V 2 R ) . Hence, power will increase

• i hope it helps you ☺️ ✌️

Answer 2

Answer:

The electric heater will release more heat when it's coil reduced.
