Question

Calculate the wattage of an electric heater which draws
5A current when connected to a 220V power supply.​

Answer 1

Answer:

the answer is 1100 watt.

Explanation:

we know that

Power = potential diff. × time

So, V=220 and I=5

therefore, power=220 × 5

=1100 watt

Answer 2

i=5A r=220v Q=5A

Explanation:

we know that v=ir

v=5×220

=1100

w=Qv

w=5×1100

=5500
