Chapter 6.3, Problem 17PP

To determine

To calculate: Current in the video-disc player.

Answer to Problem 17PP

Current in the video-disc player is $\underset{\_}{\text{0}\text{.05 A}}$ .

Explanation of Solution

Given:

Power = $6.0\text{ W}$

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:

  $\begin{array}{l}P=IV\\ I=\frac{P}{V}\\ =\frac{6.0\text{ W}}{120\text{ V}}\\ =0.05\text{ A}\end{array}$

Conclusion:

Current in the video-disc player is $\underset{\_}{\text{0}\text{.05 A}}$ .
