Expert Solution & Answer
Chapter 5, 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:
Hence, if the load drawn is 5 A with 120 V then 600 watts will be used.
