Question

what is a potential difference,please answer by ncert​

Answer 1

hey mate here is your answer of potential difference from ncert...

Potential difference between any two points is defined as the amount of work done in moving a unit charge from one point to another...

hope this answer helps you...❤❤✌✌

Answer 2

Answer:-

Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.

Potential difference = Work done /Charge.

V = W/Q

here

V is the potential difference

W is the work done

Q is the charge

✧ SI unit of electric potential energy is volt (V).

✧ 1 volt : If 1 joule of work is done in taking 1 coulomb of charge from one point to another , the potential difference between the points is 1 volt.

1 Volt = 1Joule/1Coulomb

✧ The Potential difference is measured by an instrument called the Voltameter.
