What is the ohm?
The Ohm is a unit of measure of resistance to the flow of electricity. The ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere.
Why is the potential difference between two points in a good conductor so small that it can be neglected?
Potential difference V = I R. Here I is the current passing through the conductor. R is the resistance of the conductor. In case of good conductor the resistance will be almost zero and so the product too becomes almost zero. Hence the potential difference is neglected.
Why voltage are not produce in netural wire?
First of all, by definition, 'voltage' is another word for 'potential difference', and a potential differenceexists between two different points. So a single conductor cannot experience a 'voltage' or 'potential difference'. Your question, therefore, should ask why a neutral conductor has no 'potential'. By general agreement, potentials are measured with respect to earth (ground), which is arbitrarily assumed to be at 0 volts.The answer is that a neutral conductor is earthed, or grounded, so theoretically its potential must be the same as earth -i.e. 0 volts. But, in practise, due to the resistance of the conductor that connects the neutral conductor to earth, the neutral conductor can often have a potential of several volts with respect to earth.
Explain how grounding can offer protection from electric discharges?
there are wristbands available that ground you, so any static electricity you generate is transferred away from you. Also, touching anything metal will discharge the electricity just like the wristband, however, and more you generate will be transferred to the computer component you are working with (which is where i believe you were going with this question)
Are lightning and grounding the same?
definition:Lightning is a flash of bright light in the sky which is produced by electricity moving between clouds or from clouds to the ground. so as we know already lightning is of two types direct and indirect lightning. These are anyway a discharge of electricity either positive or negative potential just discharges to ground known as lightning. definition:to put an earth wire between a piece of electrical equipment and the ground. Where as earthing is manually or artificially done to discharge any potential either to prevent any over voltages such as lightning or fault currents etc.,
What is the relationship between the electric potential inside a conductor and its surrounding environment?
The electric potential inside a conductor is constant and equal to the potential at its surface. This is because the electric field inside a conductor is zero, and any excess charge on the conductor redistributes itself to maintain equilibrium with the surrounding environment.
What do you call Electricity is the movement of what through a conductor?
Electricity is the movement of electrons through a conductor. Electrons are negatively charged particles that flow from a higher potential to a lower potential, creating an electric current.
What is the result as static electricity charges move off an object?
As static electricity charges move off an object through a discharge, the object then becomes the same potential as the surrounding objects in the area.
How is static different from electrical energy current?
Electric current is generated at a specific frequency for specific uses. Static electricity is usually a random discharge from one potential point to another.
What are the requirements for electricity to flow in a circuit?
A good conductor ana potential difference between two poles
What is the potential inside a conductor?
The potential inside a conductor is zero.
What casues electric?
Electricity is caused by the flow of electric charge (usually electrons) through a conductor. When there is a potential difference, or voltage, applied across a conductor, it creates an electric field that causes the movement of electric charge, resulting in the flow of electricity.
Why do the electrons jump in an electrostatic discharge?
Electrons jump in an electrostatic discharge because of a buildup of electric charge, creating a potential difference between two objects. When the potential difference becomes high enough, the electrons move rapidly to neutralize the charge imbalance, producing a visible discharge of electricity.
What is a buildup of electric charges called?
A buildup of electric charges is called static electricity. This occurs when there is an imbalance of positive and negative charges on an object, leading to the potential for a discharge of electricity.
Why you get shock when touching uncovered wire?
You can be shocked because that the wire is passing electricity and that its moving around. Your body has electricity in them and when touched the electricity are moved and you get shocked
When does electricity flow through a solid electrical conductor?
Electricity flows through a solid electrical conductor when a potential difference (voltage) is applied across its ends, creating an electric field that drives the movement of electrons through the conductor. The flow of electrons constitutes an electric current, which is the movement of charge that powers electrical devices and systems.
Why does lightning strike near water?
Lightning strikes strike near water because water is a good conductor of electricity. Most lightning strikes happen by the ocean because the salt makes it an even better conductor at electricity than fresh water.
