8 Electric Potential & Potential Difference

Zeta potential is the potential difference between

In figure two points A and B are located in a region of electric field . The potential difference V_(B)-V_(A) is

Are we free to call the potential of earth (+ 100 V) instead of zero ? What effect would such an assumption have on measured values of A potentials B potential difference ?

The unit of potential difference is :

Define the term potential difference.

In following circuit potential at point 'A' is zero then determine (a) Potential at each point (b) Potential difference across each resistance

For the given circuit, terminal potential differences of cells are around

Difference Between Potential Difference And Emf

Assertion: Terminal potential difference of a cell is always less than its emf. Reason: Potential drop on internal resistance of cell increases terminal potential difference.

The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the source. What current will the heater draw if the potential difference is increased to 120 V ?
