Basically, this Electric potential calculator gives us the electric potential over a particular point. Due to the utilization of this calculator, we can do the calculations directly by simply entering the amount of the charge, from a particular distance r, and clicking on the calculate button gives the Resultant Electric potential of a point charge.

In this article, we can find an electric potential calculator and a way to utilize the calculator with the related formulas, Example problems that make the operations simpler and easier.

Electric Potential - Definition

The overall work performed required moving a single charge from a reference point to a particular point that is opposite to the electric field.It units are joules / coulombs.(or) simply in volts. It is a little bit connected with the potential energy.

Electric Potential Formula

The Electric potential is calculated by using the formula V = kq/ r

  • Where k is a coulomb’s constant having its theoretical value as 1 /4.π. ϵ0 = 9.0×109
  • q is electrostatic charge and r is distance.

How do you Calculate Electric Potential?

To calculate the Electric potential follow the below steps manually when there is no calculator.

  • Determine the corresponding value of the charge.
  • Multiply the charge value with coulomb’s whose theoretical value is 1 /4.π. ϵ0 = 9.0×10^9.
  • Then divide the complete value with the given distance r in the formula V = kq/r
  • The resultant value which is obtained is nothing but the Electric potential at a given point charge.

Electric Potential Examples

Question 1.

What is the Electric potential at a point with a charge of 3 coulomb’s present having a distance of 7 centimeters?

Solution :

Given electric charge q = 3x 10^7 coulomb’s and distance(r) = 7 centimeters = 0.7 meters

As we know the formula substitute the given values in it V = Kq/r

= k .( 3 ) / (0.7)

= (9.0 x 10^9 ).(3)/(0.7)

= 38,518 x 10^6 volts

So, 38,518 volts is the Resultant electric potential at a point charge containing a distance of meters.

Question: 2.Calculate the voltage 4. Cm away from the center with a diameter of 2-centimeter metal sphere containing a charge of 4.00 nc?

Solution :

Given diameter of metal sphere = 4 centimeters

charge of metal sphere = 4.00nc

By substituting the values in calculator = kq/r

= (9.0 x 10^9 ).(4.00nc)/ (0.4m )
= 0.000008988 x 10^6 volts

Hence the overall Resultant Electric potential of the metallic sphere is = 0.000008988 x 10^6 volts

Question 3: A plastic shaped cylinder with a diameter of 0.4 cm is employed in static electricity illustration containing an evenly distributed 32 pC charge over the surface, Then calculate the electric potential?

Solution :

Given diameter of plastic cylinder = 0.4 cm

Charge of cylinder = 32 pC
As we know the formula substitute the values in calculator = kq/r

= (9.0 x 10^9 ).(32pC)/ (0.4cm )

= 0.0000719 x 10^6 volts

Hence the overall Resultant Electric potential of the plastic cylinder is = 0.0000719 x 10^6 volts
