Question

A source of 10V supplies a current of 4A for 5 minutes. How much energy is provided in this time

Answer 1

Answer:

E = 12000 j

Explanation:

energy = power * Time( in seconds)

power = VI

Answer 2

Given: A source of 10 V supplies a current of 4 A for 5 minutes

To find: Energy provided in this time

Explanation: Voltage= 10 V

Current flowing through the conductor= 4 A

Time = 5 minutes

= 5* 60 ( 1 minute= 60 seconds)

= 300 seconds

The amount of energy flowing through the conductor is the product of the power and the time duration for which the current is flowing.

Power= Voltage* Current

= 10 * 4

= 40 W

Energy= Power * Time

= 40 W * 300 seconds

= 12000 J

= 12 kJ ( 1 kJ = 1000 J)

Therefore, the energy provided in this time is 12 kJ.
