Question

If 5 J of work is needed to shift 10C of charge from one place to another. The potential difference between the places should be

Answer 1

Given:-

• Work Done ,W = 5 J

• Charge ,Q = 10 C

To Find:-

• Potential Difference between them.

Solution:-

As we know that the potential difference between two point is the amount of work done at per unit charge.

• V = W/Q

Where,

V is the potential difference

W is the Work Done

Q is the Charge

Substitute the value we get

→ V = 5/10

→ V = 1/2

→ V = 0.5 v

Therefore, the potential difference between these point should be 0.5 volts.

Extra Information !!

• The flow of charge is called current.

• The charge passing per unit time through a given place is the magnitude of electric current at that place.

• SI unit of current is Ampere (A).

• If one coulomb of charge passing through a place in one second, then the current is said to be one ampere.

Mathematical term

• I = Q/t

here,

I is the current

Q is the charge

t is the time.

Answer 2

Explanation:

Given :

• If 5 J of work is needed to shift 10C of charge from one place to another.

To Find :

• The potential difference between the places should be

Solution :

Potential difference is an electric circuit carrying some current as the work is done to move a unit from one point to the other.

• Potential difference =work done /charge

• SI unit of potential difference is volt(V)

____________________________

$: \implies \: \: \: \boxed{ \sf \: V = \frac{W}{Q} }$

Substitute all Values :

$: \implies \: \: \: \: \: \sf \: V = \frac{5}{10} \\ \\ \\: \implies \: \: \: \: \: \sf \: V =0.2$

• Hence the potential difference is 0.2
