Question

What is the energy consumed by 4 electric heaters each of power 500 W when used for 15 minutes?​

Answer 1

• Power=P=500W
• Time=15min

Total power of 4heaters

$\\ \sf\longmapsto 4(500)=2000W$

Total Time=

$\\ \sf\longmapsto 4(15)=60min=1h$

We know

$\boxed{\sf E=Pt}$

• E denotes to Energy
• P denotes to power
• t denotes to time

$\\ \sf\longmapsto E=2000(1)$

$\\ \sf\longmapsto E=2000J$
