A 10 V fan with a current of 2 A is turned on for 30 seconds. Calculate the energy transferred in joules,

E = 600 J

Explanation:

Given that,

Voltage, V = 10 V

Current, I = 2 A

Time, t = 30 s

We need to find the energy transferred. Energy transferred is calculated as follows :

Ohm's law, V = IR, R = V/I

So, 600 J of energy is transferred.
