Chapter 18, Problem 27P

To determine

The maximum power consumption.

Answer to Problem 27P

  $0.96W$

Explanation of Solution

Given info:

Current, $I=320mA=320\times {10}^{-3}A$

Voltage, $V=3.0V$

Formula used:

Electrical power:

  $P=VI$

Here, V is the voltage and I is the current.

Calculation:

Substitute the given values:

  $\begin{array}{c}P=\left(3.0V\right)\times \left(320\times {10}^{-3}\text{}A\right)\\ =\left(3.0V\right)\times \left(0.32A\right)\\ =0.96W\end{array}$

Conclusion: The maximum power consumption is $0.96W$ .
