Answer:

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  = [tex]\frac{1}{2}[/tex] c v²  

c is the quantity of charge

v is the voltage

 Potential energy   =  [tex]\frac{1}{2}[/tex] x 4 x 12²  = 288J
