Textbook Problem

A 5.00-V power supply provides a maximum current of 10.0 A. (a) Calculate the maximum power delivered by the power supply. (b) How many 2.00-W cell phone chargers could be powered by the power supply? Include fractional numbers in your answer.

(a)

To determine
The maximum power delivered by power supply.

Explanation

Given Info: Voltage provided by power supply is 5.00V and maximum current can flow is 10.0A .

Explanation:

Formula to calculate the maximum power is,

Pmax=ImaxΔV

  • Pmax is the maximum power,
  • Imax is the maximum current,
  • ΔV voltage provided by power supply

Substitute 10.0A for Imax and 5

(b)

To determine
The maximum number of cell phone chargers that can be powered by the power supply.
