Answer 2

Given data: Power of 1.5 kW toaster and current 12 A.

To find: The voltage drop across 1.5 kW toaster that draws 12 A current.

Solution:

To convert 1.5 kW to watt, the general formula is, 1kW = 1000 watts.

1.5 kW=1500 watts.

The formula for power is, $P=VI$

To find voltage V, the formula can be written as,

$V=\frac{P}{I}$

Substitute $P=1500 watts, I=12A$

$V=\frac{1500}{12}$

$V=125$ $volts$.

Therefore, the voltage across a 1.5 kW toaster that draws 12 A of current is (b) 125V.
