Question

How long will it take, in minutes, for a transformer to transfer 2.3 X 10^6 J of energy from a 120-V circuit to a 345-V circuit with a current of 1.5 A?

Answer 1

Answer:

e

Explanation:

Answer 2

It will take 74.07 minutes, for a transformer to transfer 2.3 X 10^6 J of energy from a 120-V circuit to a 345-V circuit with a current of 1.5 A

What is power?

The rate of doing work is known as power. The Si unit of power is the watt.

Power =work/time

The mathematical expression for the power is as follows

P = VI

where P is the power

V is the voltage

I is current passing through the circuit

For a transformer to transfer 2.3 X 10^6 J of energy from a 120-V circuit to a 345-V circuit with a current of 1.5 A

Power on the delivery side of the transformer by using the above formula

P = VI

P= 345 V × 1.5 A

P= 517.5 watt

Power = electrical energy /time

517.5 watt = 2.3 X 10^6 J / time

time = 4444.44 seconds

       =74.07 minutes
