What is the electric potential difference? Electric potential: The electric potential is defined as the amount of work required to move a unit charge from a reference point to any specific point in the presence of an electric field. It is also defined as the electric potential energy per unit...
It is the amount of work done on a charge to move it from a reference point to a specific point. V=kqr Where k is coulomb's constant. q is the magnitude of the charge. r is the specific point.Answer and Explanation: Electric Potential: It is the amount of work required to move...
If two points in a circuit are at the same potential, then the current cannot flow. The magnitude of a current depends on the voltage or potential difference between two points. Hence, we can say the current is the effect of voltage. Electric current can produce electromagnetic fields, which...

In the hydrogen atom, what is the electric potential energy of the electron when it is found in the n = 3 state? Hint: refer to the derivation of the total energy for energy proportions. In the hydrogen atom, what is the electric potential energy of the electron when it is...
There is a relationship between electric potential and electric current. This relationship was first demonstrated experimentally by a scientist named George Simon Ohm. What is the difference between electric current and electron flow? Why are they in different directions?
场强为零,电势不一定为零,因为电势是个相对量 The electric potential is, with the gravitational potential energy which relative says is same, does not have the frame of reference has no way to say its potential energy is how many. Likewise does not select a zero potential spot, is does not ...
What is electric field strength? Electric field strength is a quantitative expression of the intensity of an electric field at a particular location. The standard unit is the volt per meter (V/m or V·m-1). A field strength of 1 V/m represents a potential difference of 1 V between poin...
In electrical circuits, power is measured in volts (V), as well as in amperes (A). A volt is the unit of electric potential difference. Another way to explain volt is the force that sends electrons through an electrical circuit to establish an electric current that's measured in amperes....
Voltageis the electric potential difference per unit charge between two points in an electric field. It’s generated by the movement of electrons, which are charged particles. The movement of electrons creates a difference in potential energy between two points. We call this potential difference vol...
