Question

12 J of work has to be done against an existing electric field to take a charge of 0.01 C from A to B. How much is the potential difference VB − VA?

Answer 1

Potential difference, $\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{A}}$ is 1200 volt.

Explanation:

Given data in questions  :

Now,

Potential difference =  $\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{A}}$

Potential difference :

When charge travels around a circuit, each charging coulomb has less energy potential, so voltage decreases (relative to power source).

The difference between the electric potential at two points in a circuit is known as the potential difference.

Given values in the question :  

               q is the electric Charge  

               q = 0.01 C

Work done = 12 J  

Now,  

Work done = Potential difference × electric Charge

                 Potential difference = $\frac{\text {Work done}}{\text {electric Charge}}$

                  Potential difference = $\frac{12}{0.01}$

                  Potential difference = $1200 volt$

Thus, the potential difference, $\mathrm{V}_{\mathrm{B}}-\mathrm{V}_{\mathrm{A}}$ = 1200 volt.

Answer 2

Answer:

1200 volts is the answer

Explanation:

Potential difference,  is 1200 volt.

Explanation:

Potential difference =  

Potential difference :

When charge travels around a circuit, each charging coulomb has less energy potential, so voltage decreases (relative to power source).

The difference between the electric potential at two points in a circuit is known as the potential difference.

Given values in the question :  

              q is the electric Charge  

              q = 0.01 C

Work done = 12 J  

Now,  

Work done = Potential difference × electric Charge

                Potential difference =  

                 Potential difference =  

                 Potential difference =  

Thus, the potential difference,  = 1200 volt.
