What is potential energy per unit charge?
The electric potential.
What are factors that determine the size of the electric potential and electric potential energy?
Mass and Charge
How can electric potential be high when electrical potential energy is realitively 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 the voltage at the location of a 0.0001-Coulomb charge that has an electric potential energy of 0.5 joules?
Electric Potential = Electrical Potential Energy/ Charge The measurement for electric potential is call the volt. Electrical Potential is often called voltage. Voltage or Electrical Potential = 0.5 Joules / .0001 Coloumb = 5000
What is the amount of energy in an electric charge?
zero. Energy is the product of charge and voltage, E=ev. No voltage means no energy in charge.

What is volt of electricity?
Voltage is the measure of the electric potential difference between two points in an electric circuit. It is the amount of potential energy per unit charge available to move electrons from one point to another. Voltage is measured in units called volts, symbolized by the letter V.
Define voltage in terms of electric potential energy and charge?
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
What is the formula for potential energy in an electrical system?
In an electric circuit, potential energy is usually understood as "stored charge." This is what capacitors do.
What must a charge have to move and to transfer energy?
A path to follow and electric potential.
What has potential energy?
Potential energy is a energy stored within a system as a result of the position or configuration of the different parts of that system.The types of potential energy are gravitational potential energy, which is energy due to height, and elastic potential energy, which is energy involved with a stretched or compressed spring.
What Electrical potential energy?
Electric potential is like electric potential energy, except electric potential energy requires that you have at least two charged particles: one charged particle (can be considered to be stationary) to produce the electric field and another charged particle to be affected by that electric field. If both charged particles are positively charged, then when you move the nonstationary charged particle closer to the stationary charged particle, potential energy of the system increases, because the charged particles naturally want to repel. However, let's say you remove that nonstationary charged particle and are left with just the single charged particle. There is no more potential energy in the system, because there is no other charged particle to be acted upon by the electric field. However, the single charged particle still emits an electric field. This field is what creates "electric potential." Even though there is no second particle in the system, if you were to place a second particle into the system (let's call it a test particle), its potential energy would be equal to the electric potential multiplied by the charge of the test particle. U = kq1q2/r (electric potential energy with 2 charges, where the 0 of potential energy is infinitely far away) V = kq1/r (electric potential requiring only 1 charge) V = U/q2 (electric potential is potential energy without the second charge) U = Vq2 (electric potential energy is electric potential multiplied by second charge) There is also a concept called gravitational potential, where it's gravitational potential energy divided by the test mass. It can be a negatively charged particle. In that case, electric potential decreases as you get closer to the negatively charged particle. Even though electric potential decreases, if you have two negatively charged particles, electric potential energy increases as you move the 2nd negative charge closer to the first charge. This is because multiplying 2 negative charges makes a positive: U = k(-q1)*(-q2)/r = kq1q2/r (assuming q1 and q2 are the charge magnitudes) So in this case, it's a little weird because that's how the math works. Nature has a tendency to reduce potential energy, but potential is different and doesn't work the same way. However if the test charge was positive, the sign of electric potential energy will be the same as electric potential with respect to location. V = k(-q1)/r = -kq1/r U = k(-q1)(q2)/r = -kq1q2/r Potential energy is not the same as potential! They are related, but don't get them confused. Energy is measured in Joules. Potential is measured in Volts. Completely different units. Volts = Number of Joules / Number of Coulombs. Electric Potential = Electric Potential Energy / Charge of Test Particle
What is a capacitance?
capacitanceis the ability of a body to store charge in anelectric field. Capacitance is also a measure of the amount of electric potential energy stored (or separated) for a given electric potential.AnswerA capacitor is a device that will store electrical energy. This energy is stored in its electric field. This is achieved by separating the charge on its plates -contrary to popular belief, it does not store that charge, as the net charge remains the same after charging as it was before charging.
