Question

Alculate the potential difference if 20J of energy are transferred by 8C of charge.

Answer 1

Given :

• ✧ Energy transferred = 20J
• ✧ Charge = 8C

To Find :

• ✧ Potential difference

Using Formula :

We know that the electric potential difference is also known as voltage (v).

`{\star{\small{\underline{\boxed{\sf{\red{ V =(E)/(Q)}}}}}}}`

• ✧ Potential difference
• ✧ E = Energy transferred
• ✧ Q = Charge

Solution :

Substituting the given values in the formula to find potential difference :

`{\dashrightarrow{\small{\pmb{\sf{ V =(E)/(Q)}}}}}`

`{\dashrightarrow{\small{\sf{ V =(20)/(8)}}}}`

`{\dashrightarrow{\small{\sf{ V = \cancel{(20)/(8)}}}}}`

`{\dashrightarrow{\small{\sf{ V = {(10)/(4)}}}}}`

`{\dashrightarrow{\small{\sf{ V = \cancel{(10)/(4)}}}}}`

`{\dashrightarrow{\small{\sf{\underline{\underline{\purple{V = 2.25}}}}}}}`

Hence, the potential difference is 2.25V.

Answer 2

V = 2.5 J/C

Step-by-step explanation:

Given:

Energy = E = 20 J

Charge = Q = 8 C

Required:

Potential Difference = V = ?

Formula:

V =
`(E)/(Q)`

Solution:

V = 20/8

V = 2.5 J/C
