6 Volt battery


3 Volt battery


Sagot :

Answer:

Explanation:

Given parameters:

Electrical energy  = 18J

Quantity of charge Q = 12C

Unknown:

Voltage  = ?

Solution:

The expression of electrical potential energy is given as:

      Electrical potential energy  = [tex]\frac{1}{2}[/tex] c v²

c is the quantity of charge

v is the voltage

           18  =  [tex]\frac{1}{2}[/tex]  x 12 x v²  

           18 = 6v²  

              v² = 3  

               v = 1.7v
