Question

(c) What is the potential difference between the terminals of a battery if 250 joules of work is required
​

Answer 1

Answer:

12.5

Explanation:

Potential Difference \longrightarrow⟶ 12.5

Explanation:

Given:

Work Done \longrightarrow⟶ 250J

Charge \longrightarrow⟶ 20C

To Find:

Potential Difference, i.e, Voltage.

Solution:

We know that,

\sf Volt = \dfrac{Workdone}{Charge}Volt=

Charge

Workdone

Now, we substitute the given values in the equation above.

\sf V = \dfrac{250}{20}V=

20

250

'0' gets cancelled,

\sf V = \dfrac{25}{2}V=

2

25

V = 12.5

Answer 2

Explanation:

The potential difference flowing between the terminals of a battery when 250 joules of work is done to move a charge of 20 C is is 12.5 v
