Question

A) write two points of difference between Electric
Energy & Electric power
B) out of 60w & 40w lamps Which
one Has Higher Elecerical Resistance when in use​

Answer 1

Answer:

B) Resistance is inversely proportional to the power so 40w have more resistance

Answer 2

Answer:

Explanation:

(A).

Two differences between electric energy and electric power are : Electrical power is the rate of amount of electrical energy transferred. Electrical energy is the energy generated as the result of the potential difference in a circuit which causes current to flow through it. Energy is measured in joules.

(B).

The bulb with 40 W has higher electrical resistance. , the voltage supplied will be constant denoted as V. So, the resistance for 60 W bulb is 2/3rd times less than the resistance for 40 W bulb. Thus, the 40 W bulb has higher resistance.
