Question

the electrical energy consumed by a 30 W bulb in 5 minutes is

Answer 1

Here is ur answer...........

Given,

P = 30W

t = 5 min = 300 sec

Electrical energy consumed,

E = Pt

E = 30 × 300 = 9000J.

Hope it helps!

Answer 2

The electrical energy consumed by a 30W bulb in 5 minutes is 9000 J

Given :

A 30W bulb in 5 minutes

To find :

The electrical energy consumed by a 30W bulb in 5 minutes

Solution :

Step 1 of 2 :

Write down power and time

Power = P = 30W

Time = t = 5 minutes = 300 seconds

Step 2 of 2 :

Calculate electrical energy consumed

The electrical energy consumed

= E

= Power × Time

= P × t

= 30 × 300 J

= 9000 J
