Chapter SH, Problem 6.4APP

To determine

To calculate: Power supplied to an appliance.

Answer to Problem 6.4APP

Power supplied to the appliance is $\underset{\_}{360\text{ W}}$ .

Explanation of Solution

Given:

Voltage difference = $\text{120 V}$

Current = $\text{3}\text{.0 A}$

Formula used:

Power is given by,

  $P=IV$

WhereI is current andV is voltage difference.

Calculation:

Power is calculated as:

  $\begin{array}{l}P=IV\\ P=\left(3.0\text{ A}\right)\left(120\text{ V}\right)\\ P=360\text{ W}\end{array}$

Conclusion:

Power supplied to the appliance is $\underset{\_}{360\text{ W}}$ .
