Question

An electric heater is rated 1500 W. How much energy it use consumed 12 hours?​

Answer 1

Given ,

Power (P) = 1500 w

Time (t) = 12 hr = 43200 sec

As we know that ,

$\boxed{ \sf{Electric\: energy = Power × Time }}$

Thus ,

Electric energy = 1500 × 43200

Electric energy = 64800 Kilo joule

Therefore ,

• The 64800 Kilo joule of electric energy consumed by heater in twelve hours

Answer 2

Given :

• Power 1500 W
• Time 12 hours [We will convert it in seconds = 43200 seconds]

To find :

• Electric energy

Formula used :

• Electric energy = Power × Time

According to the question,

↦ Electric energy = Power × Time

↦ Electric energy = 1500 × 43200

↦ Electric energy = 64800 kJ (Kilojoule)
