Question

A 60 w lamp is connected to 240v supply.It draws.....Current and .....Energy is used by the lamp in 6h.

Answer 1

Answer:

I = 0.25 A                &             E = 3.6 kwh

Explanation:

P = 60 w

V = 240 v

t = 6 h

I = ?

E = ?

P = V I

I = P / V

I = 60 / 240

I = 0.25 A

E = P t

E = 60 x 6 / 1000

E = 3.6 kwh
