## Which point A or B has the higher electric potential Why?

We say that **point A is at a higher potential than point B**. Positive charges, starting from rest, will accelerate from regions of high potential and move toward regions of low potential. Negative charges, starting from rest, will accelerate from regions of low potential and move toward regions of high potential.

## What is the potential difference between A and B?

The potential difference between the points A and B is equal to **V=I×5r4**.

## What is the electric potential at point B?

The radius at point B is the same as in point A, hence potential energy of an electron at point B is the same as at point A. The potential energy of an electron at point B in the figure – **2.88 × 10 ^{–}^{16} J**.

## How can electric potential be high when electric potential energy is relatively low?

Electric potential can be high when electrical potential energy is relatively low **if the charge is low as well**. … It is correct to say that an object with twice the electric potential of another has twice the electrical potential energy only if the charges are the same.

## What is difference between electric potential and potential energy?

The basic difference between electric potential and electric potential energy is that Electric potential at a point in an electric field is the amount **of work done to bring the unit positive charge from infinity to that point**, while electric potential energy is the energy that is needed to move a charge against the …

## How electric potential is created?

The potential energy for a positive charge **increases when it moves against an electric field** and decreases when it moves with the electric field; the opposite is true for a negative charge. Unless the unit charge crosses a changing magnetic field, its potential at any given point does not depend on the path taken.

## What is the potential difference between points A and B capacitor?

**VAB=22V**.

## What is the potential difference across the capacitor?

The capacitor is uncharged, so its **potential difference is zero**. The closed switch has no potential difference, so by the loop rule the potential difference across the resistor equals the emf of the battery.

## Why does electric potential decrease with distance?

Actually, electric potential **decreases as you move farther from a charge distribution**. … That’s because like charges repel each other, so it takes more and more energy to move the charges together the closer you get.

## What is the potential difference across the plates?

The electrical potential difference between the two plates is expressed as **V=Ed**, the electric field strength times the distance between the plates. The units in this expression are Newtons/coulomb times meters, which gives the final units Joules/coulomb.
