Question

When 3 J of work is done in moving a 6 C of charge across two points connected through a battery, then find the potential difference of the battery

Answer 1

Answer:

• 0.5 Volts is the required Potential Difference.

Explanation:

Given:-

• Work Done ,W = 3 J

• Charge ,Q = 6 C

To Find:-

• Potential Difference ,V

Solution:-

Electric Potential Difference is defined as the work done to move charge from one point to another.

• W = VQ

→ V = W/Q

where,

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

Substitute the value we get

→ V = 3/6

→ V = 1/2

→ V = 0.5 v

• Hence, the potential difference of the battery is 0.5 Volts.

Answer 2

Given :-

Work Done = 3 J

Charge of Car = 6 C

To Find :-

Potential Difference

Solution :-

As we know that

V = W/Q

Here,

V is the Potential difference

W is the Work done

Q is the Charge

$\sf V = \dfrac{3}{6}$

$\sf V = 0.35 Volts$

Extra Bytes :-

• Volts is the SI unit of voltage.
• Voltage and Potential Difference are same.
• Joule is the unit of Work
• Coulombs is the unit of charge.
