Question

The work done in moving a charge of 2C across two points having a potential difference 12V is

A) 24 J

B) 6 J

C) 14 J

D) 10 J​

Answer 1

Answer:-

• Charge=Q=2C
• Voltage=V=12V
• Work done=W=?

We know that

$\boxed{\sf V=\dfrac{W}{Q}}$

$\\ \qquad\quad\sf\rightarrowtail W=VQ$

$\\ \qquad\quad\sf\rightarrowtail W=12\times 2$

$\\ \qquad\quad\sf\rightarrowtail W=24J$

Note:-

SI unit of Work done is Joules(J)

Answer 2

Given:-

• Charge ,Q = 2 C
• Potential Difference ,V = 12v

To Find:-

• Work Done ,W

Solution:-

According to the Question

It is given that charge of 2C across two points having a potential difference 12V . We have to calculate the work done in moving charge .

As we know that potential Difference is define as the work done per unit charge.

• V = W/Q

where,

• V denote Potential Difference
• W denote Work done
• Q denote Charge

Substitute the value we get

$\longrightarrow$ 12 = W/2

$\longrightarrow$ 12 × 2 = W

$\longrightarrow$ W = 12×2

$\longrightarrow$ W = 24 J

• Hence, the work done in moving charge is 24 Joules.

So, the required option is ( A ) 24 Joules.
