Chapter 4, Problem 1TC

Explanation of Solution

Given: Load drawing is 5 A with 120 V.

To find:If the load drawn is 5 A with 120 V, then how much power is used.

Solution:

Here,

A represents ampere, which is the unit of current.

V represents volt, which is the unit of voltage.

W represents watt, which is the unit of power.

Now, the formula for the power is:

$\begin{array}{c}\text{Power}\left(w\right)=\text{Current}\left(A\right)\times \text{Voltage}\left(v\right)\\ =5\times 120\\ =600\text{ watts}\end{array}$

Hence, if the load drawn is 5 A with 120 V then 600 watts will be used.
