What will be the energy generated when a 5A current flows through a resistor of 10 ohm for 20 minutes?​

Answer 1

Explanation:

What will be the energy generated when a 5A current flows through a resistor of 10 ohm for 20 minutes?

☆

Energy-power*time.

E=P*t.

Power in watts.

time in seconds.Power-(current)*(current)* resistor.

P=(1)^2*R.P=(5*5)*2.P=50

Watts.Time=t=30mins=30*60seconds=1800secs.

Energy=E=P*t. E=50*1800.E=90000 joules.

○E=90kilo joules.E=90k joules.○
