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 ​

Answer 1

Answer:

we know that

power:- Energy consumed per unit second or the rate at which the work is done is called power

P = W/t

P = 500W = 0.5KW

Time = 2 × 10 = 20h

P = W/t

W = Pt

W = 0.5 × 20

W = 10KWh

We know that 1000W = 1KW = 1unit

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