A battery-powered global positioning system (GPS) receiver operating on 9.0 V draws a current of 0.13 A. How much electrical energy does it consume during 1.5 h?

Respuesta :

Answer:

6318 Joules

Explanation:

V = Voltage = 9 V

I = Current = 0.13 A

t = Time the GPS is used = 1.5 hours

Power

[tex]P=V\times I\\\Rightarrow P=9\times 0.13\\\Rightarrow P=1.17\ W[/tex]

Energy is obtained when power is multiplied with time

[tex]E=Pt\\\Rightarrow E=1.17\times 1.5\times 60\times 60\\\Rightarrow E=6318\ J[/tex]

∴ Electrical energy the GPS uses is 6318 Joules
