A device experiences a voltage drop of 5.0 V across it while a current of 10.0 mA flows through it. How much power does it dissipate? Show all work and include units of measure.

Respuesta :

Answer:

0.05 W

Explanation:

The power dissipated by a device can be written as

[tex]P=VI[/tex]

where

P is the power dissipated

V is the voltage drop on the device

I is the current flowing through the device

In this problem, we have

V = 5.0 V is the voltage drop across the device

I = 10.0 mA = 0.01 A is the current through it

By applying the formula, we find the power dissipated:

[tex]P=(5.0 V)(0.01 A)=0.05 W[/tex]
