Question

An electric kettle of 500w is used to heat water everyday for 2hours. calculate the number of unit of electrical energy consumed it in 10 days​

Answer 1

Step-by-step explanation:

=P = W/t

=P = 500 W = 0.5 KW

------>Time = 2 × 10 = 20 h

=P = W/t

=W = Pt

=W = 0.5 × 20

=W = 10 KWh

------>We know that 1000 W = 1 KW = 1 unit

∴ 10×1 = 10 unit of energy is consumed by electric kettle
