Question

An electric device consumes 4500 J of energy in 30 minutes while operating at 24 V. Calculate the current drawn by the device.​

Answer 1

Answer:-

• Energy consumed=4500J
• Time =30min=1800s

We know that

$\boxed{\sf Power\: Consumed=\dfrac{Energy\: Consumed}{Time}}$

$\\ \sf\longmapsto Power\: Consumed=\dfrac{4500}{1800}$

$\\ \sf\longmapsto Power\: Consumed=2.5watt$

• Potential Difference=24V
• Current=I=?

$\boxed{\sf P=VI}$

$\\ \sf\longmapsto I=\dfrac{P}{V}$

$\\ \sf\longmapsto I=\dfrac{2.5}{24}$

$\\ \sf\longmapsto I=0.1A$
