Question

3. Calculate the consumption of electrical energy for a month of an appliance of a 150 wa running 8 hours a day.​

Answer 1

P = 150 watt

t = (8 × 30) hr = 240 hr

Energy consumed by an electrical appliance is given by

E = VIt

But we know that, Power, P = VI

Therefore, E = P × t

=> E = 150 × 240

=> E = 36000 Watt Hour

=> E = 36 Kwh

Answer 2

Answer:

p = 150 watt

t = (8×30) hr =240
