Chapter 6.3, Problem 28R

To determine

To calculate: Current in a desktop-computer.

Answer to Problem 28R

Current in the desktop-computer is $\underset{\_}{\text{1}\text{.5 A}}$ .

Explanation of Solution

Given:

Power = $\text{180 W}$

Voltage difference = $\text{120 V}$

Formula used:

Power is given by,

  $P=IV$

where $I$ is current and $V$ is voltage difference.

Calculation:

Current is calculated as:

  $\begin{array}{l}P=IV\\ I=\frac{P}{V}\\ =\frac{\text{180 W}}{120\text{ V}}\\ =1.5\text{ A}\end{array}$

Conclusion:

Current in the desktop-computer is $\underset{\_}{\text{1}\text{.5 A}}$ .
