What is the charge on each plate of the capacitor?
Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero.
Can there be potential difference between two neighboring conductors carrying equal +ve charges?
Yes, there can be potential difference between two adjacent conductors carrying the same charge. This is because the sizes of the conductors might be different , and hence their capacities may be different.
Can there be a potential difference between them?
Yes, if the sizes are different. of conductor and V is the potential of the conductor. The capacity of conductor depends on its geometry, so two adjacent conductors carrying the same charge of different dimensions may have different potentials.
Can there be a potential difference between two conductors of?
Yes, The potential of a conductor depends not only on the net charge but also on its geometrical shape and size. So two different conductors of different shape and size will have different potentials even if they carry equal charges.
Can two points of the same conductor have different electrical potentials?
Given that the electric field is constantly 0 for any location within the charged conductor, it is impossible for potential difference in that same volume to have any value other than 0. For points outside a conductor, potential is nonzero and can be calculated according to field and distance from the conductor.
Which two points have the same potential?
2 Answers. Two different points in a circuit can have the same electric potential in the same way that two different points on a high shelf have the same gravitational potential. If you lift a book up to point 1 on the shelf, you must do some work to overcome gravity.
What is the relationship between voltage and electrical field?
The relationship between the electric field and the voltage difference (derived in the lecture) is given by the following equation: the voltage difference between two points is equal to the integral of the dot product of the electric field and the infinitesimal distance between those two points.
What flows in a wire?
Electric current (electricity) is a flow or movement of electrical charge. The electricity that is conducted through copper wires in your home consists of moving electrons. The wire is “full” of atoms and free electrons and the electrons move among the atoms.
Do electrons actually flow in a wire?
Electrons do not move along a wire like cars on a highway. Actually, Any conductor (thing that electricity can go through) is made of atoms. Each atom has electrons in it. If you put new electrons in a conductor, they will join atoms, and each atom will deliver an electron to the next atom.
How does charge flow in a wire?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Does current flow in neutral wire?
So the voltage of the neutral wire is always zero… If it’s not small enough to be ignored, it means that the neutral wire is too small (diameter) for the amount of current that it’s carrying. current flows because of voltage. Well, yes, but no.
Does the neutral wire carry a current?
The neutral wire in a circuit carries the same current as the hot wire. Current goes out to the load and must return. That’s why the neutral wire must be the same size.
What is the purpose of a neutral wire?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.
What happens if neutral touches ground?
The neutral is always referenced to ground at one, and ONLY one, point. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current.
What happens if neutral is not grounded?
Grounding neutral provides a common reference for all things plugged into the power system. That makes connections between devices safe(r). 2. Without a ground, static electricity will build up to the point where arcing will occur in the switchgear causing significant loss in transmitted power, overheating, fires etc.
Why are neutral and ground tied together?
Commonly the neutral is grounded (earthed) through a bond between the neutral bar and the earth bar. The connection between neutral and earth allows any phase-to-earth fault to develop enough current flow to “trip” the circuit overcurrent protection device.
What is the difference between a ground and a neutral?
A Neutral represents a reference point within an electrical distribution system. A Ground represents an electrical path, normally designed to carry fault current when a insulation breakdown occurs within electrical equipment.
