Question

A 12 volt battery will increase the potential energy of 4 coulombs of charge by _____ Joules.

Question 8 options:

16 J


3 J


.33J


48 J

Answer 1

Step-by-step explanation:

Given parameters:

Voltage = 12V

Quantity of charge = 4C

Unknown:

Potential energy = ?

Solution:

Within this circuit, the value of the potential energy can be found using the expression below:

Potential energy =
`(1)/(2)` c v²

c is the quantity of charge

v is the voltage

Potential energy =
`(1)/(2)` x 4 x 12² = 288J
