Question

What power (in kW) is supplied to the starter motor of a large truck that draws 260 A of current from a 25.5 V battery hookup

Answer 1

The power is 6.63 kW.

Step-by-step explanation:

Current, I = 260 A

Voltage, V = 25.5 V

Power of an electrical appliance is given by

P = V I

P = 25.5 x 260

P = 6630 W

1 kW = 1000 W

So, the power is

P = 6.63 kW

Answer 2

P = 6.63 kW

Step-by-step explanation:

Given that,

Current, I = 260 A

Voltage of the battery, V = 25.5 V

We need to find the power supplied to the starter motor. We know that,

P = VI

Put all the values,

P = 25.5 × 260

P = 6630 W

or

P = 6.63 kW

So, the power supplied to the motor is 6.63 kW.
