Question

Find the work done in moving a charge of 3 coulomb from a point P at 220 volt to a point Q at 320 volt​

Answer 1

Hi friend here is your answer.......

here we have Q(charge) = 3coulomb

V(potential difference)= 320V - 220V = 100V

we want work done so by using

W = VQ

W= 3 into 100

W = 300 j

hope it helps dear

Answer 2

Answer:

Given:

Point P has potential of 220 V , Point Q has potential 320 V. Charge transported = 3C

To find:

Work done.

Concept:

We define potential Difference as the work done in transporting a unit positive charge from one point to another.

Mathematically , we can say :

$\boxed{ \sf{ \red{potential \: diff = \dfrac{work}{charge} }}}$

Calculation:

As per the question , putting the values :

$\sf{ \blue{potential \: diff = \dfrac{work}{charge} }}$

$\sf{ \blue{= > 320 - 220 = \dfrac{work}{3} }}$

$\sf{ \blue{ = > 100 = \dfrac{work}{3} }}$

$\sf{ \blue{= > work = 3 \times 100}}$

$\sf{ \blue{ = > work = 300 \: joule}}$

So final answer :

$\boxed{ \sf{ \green{ \huge{work = 300 \: joule}}}}$
