Define the potential difference between two points.

How is a voltmeter connected in the circuit to measure the potential difference between two points?

A charge 3 coulomb experiences a force 300 N when placed in a uniform electric field. The potential difference between two points separated by a distance of 10 cm along the field line is:

What is meant by saying that the potential difference between two points is 1 V?

If the work done to take 3 C electric charge from one point to another point is 15 J, what will be the potential difference between these two points?

An irregular shaped non conductor has some charge distribution. The potential difference between the two points A and B in it is V. If it is now enveloped in an spherical non conducting shell having uniform charge distribution in it, the new potential difference between the points (neglect any induction due to presence of charge)

On moving a charge of 20 coulomb by 2 cm , 2J of work is done , the potential difference between the points is .

The resistance of a 10 m long potentiometer wire is 20 Omega . It is connected in series with a 3 V battery and 10 Omega resistor. The potential difference between two points separated by distance 30 cm is equal to .......

Calculate the value of current and indicate its direction Also calculate the potential difference between the points (i) B & A (ii) A & C

An electric charge 10^(-3) muC is placed at the origin (0, 0) of X-Y co-ordinate system. Two points is A and B are situated at (sqrt(2),sqrt(2)) and (2, 0) respectively. The potential difference between the points A and B ,will be ......
