Use the electric potential calculator to determine the electric potential at a point either due to a single point charge or a system of point charges. You can also use this tool to find out the electrical potential difference between two points.. If you want to calculate the electric field due to a point charge, check out the electric field calculator. ...
It can be obtained by dividing the electric potential energy by the magnitude of the test charge. V = U/q 1. Or, V = kq 1 /r Replacing k by 1/(4πε o) and q 1 by Q, we get the formal expression of the electric potential.. V = Q/(4πε o r). Unit: Volt (V) or Joule/Coulomb (J/C). Dimension: [ML 2 T-3 A-1]. Symbol: V. The above equation gives the electric potential at a distance r from the ...
Our electric potential calculator can obtain the electric potential at any distance from a single point charge or a number of point charges (up to ten). If you don't know what the electric potential is, don't worry. Within this short article, we will cover: Electric potential definition; Electric potential formula/equation;
Electric Potential Energy Equation. The formula of electrostatic potential energy, written U for charged particles, accounts for both the magnitude and polarity of the charges and their separation: \(U = \frac{kQq}{r}\) If you recall that work (which has units of energy) is force times distance (F·d), this explains why this equation differs from the force equation only by an r in the denominator.
For example, a uniform electric field \(\mathbf{E}\) is produced by placing a potential difference (or voltage) \(\Delta V\) across two parallel metal plates, labeled A and B. (Figure \(\PageIndex{1}\)) Examining this will tell us what voltage is needed to produce a certain electric field strength; it will also reveal a more fundamental ...
Electric Potential. Electric potential is the work done per unit test charge by an external agent in moving the test charge from one point to another point under a constant electric field. Since the potential energy is a scalar quantity, the electric potential is also a scalar quantity. The SI unit for electrical potential is Volt (V).
Then, the net electric potential V P V P at that point is equal to the sum of these individual electric potentials. You can easily show this by calculating the potential energy of a test charge when you bring the test charge from the reference point at infinity to point P :
Problem Statement: Two point charges q 1 = q 2 = 10-6 C are located respectively at coordinates (-1, 0) and (1, 0) (coordinates expressed in meters). Calculate: The electric potential due to the charges at both point A of coordinates (0,1) and B (0,-1). The work done by the electric force to move the electric charge q 0 = – 2 10-9 C from point A to point B. ...
The potential at infinity is chosen to be zero. Thus, for a point charge decreases with distance, whereas for a point charge decreases with distance squared: Recall that the electric potential is a scalar and has no direction, whereas the electric field is a vector. To find the voltage due to a combination of point charges, you add the individual voltages as numbers.

Since we have already worked out the potential of a finite wire of length \(L\) in Example \(\PageIndex{1}\), we might wonder if taking \(L \rightarrow \infty\) in our previous result will ...

Even our electric potential calculator verifies the same fact as it calculates positive potential due to a positive point charge and vice versa. Electric Potential Due To a System of Charges: Consider we have different point charges that are causing the electrical potential! Now here, each charge puts pressure on the point charge that can ...
