Question

a 3.6 - volt battery is used to operate a cell phone for 5.0 minutes. if the cell phone dissipates 0.064 watt of power during its operation, the current that passes

Explanation:

Step1: Recall the power formula

Power \( P = VI \), where \( P \) is power, \( V \) is voltage, and \( I \) is current. We need to solve for \( I \), so \( I=\frac{P}{V} \).

Step2: Substitute the given values

Given \( P = 0.064\space W \) and \( V = 3.6\space V \). Then \( I=\frac{0.064}{3.6}\approx0.018\space A \).

Answer:

0.018 A
