Why electric field is negative gradient of electric potential?
This is because potential decreases if we move further from a positive plate
Why the deionised water still can be dangerous with the electrical appliances?
Even deionized water can be dangerous with electrical appliances because many such appliances contain nearby surfaces with a sufficiently high electrical potential difference between them to ionize water itself and thereby make the water electrically conducting.
What is the electric field half way to the centre of a conducting sphere charged to a potential of 15v?
electric field inside the conducting sphere is ZER0..! because their are equivalent charges all around the sphere which makes the net force zero hence we can say that the electric field is also zero.!
Why is copper commonly use to make electric wires?
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.
Temporary earth bonding?
Temporary earth bonding is when you attach certain metal objects in a dwelling after removing the previous connector (eg. steel bath) with an earthing continuity cable (coloured green and yellow). This then allows work to take place on the designated faulty area. The earth in electrical terms, carries no current, and it is this that electricity will make a dash for when it is allowed to escape from its secure home in an electric cable or flex. This is because one side of the electrical supply, the neutral, is intentionally connected to earth. If someone touches a live conductor then a current will flow through the person, their shoes, the floor, the wall, via earth and back to the supply transformer via one or more earth connections of the transformer neutral. The person has completed the electrical circuit. Should any fault develop in an electrical system the electricity will always head for earth, taking the easiest route there. The electrical appliances and supplies in the home are of a much higher potential and if any of these become available to touch and are electrically charged at a different voltage to earth the possibility of an electric shock exists, with the current passing through the connection between the charged parts and earth. For instance, a person comes into contact with a conductive part that is at a potential difference to earthed metalwork and that metalwork; then a very serious shock can result. In order to eliminate this possibility, all electrical earths of circuits supplying equipment in the bathroom and all extraneous conductive parts are bonded together. In this way, even if a potential does develop, such as during an earth fault on one of the electrical circuits. Should any electrical leakage occur the leaking current will try and find a passage to earth. It is therefore important that precautions are taken to ensure.
Are Charges in an electric circuit flow because of a difference in electrical potential energy true or false?
TRUE
True or false are charges in an electric circuit flow because of a difference in electrical potential energy?
TRUE
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.
Explain why an electric discharge occurs?
Because there is a potential difference between two objects.

Difference in electrical potential between two points?
The electrical potential of a point is a value that is related to how much potential energy a charged particle at that position has, based on the electric field around it (it is however not the same as the potential energy). Electric fields are conserved force fields. What this means is that, if you go from one place to another, it does not matter which way oyu take, the energy it takes depends only on the start and end positions. This also applies to the potential (in fact, the potential wouldn't exist if it wouldn't). So to find the difference in potential, you just subtract the potential at one point from the potential at the other point. This simple subtraction is only possible because the potential is conservative. If you travel from your house to the supermarket, the energy it takes you very much depends on which road you choose. Because of that, you can't say what the energy difference (related to potential) is between your house and the supermarket without specifying how you travel.
Why you get an electric shock if you touch live and neutral wire?
Because there is a potential difference between the live and neutral wires.
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What does voltage cause the flow of?
there is a difference in electrical potential energy.
What is single electrode potential?
An electrode potential is the potential difference that develops when an electrode of one element is placed in a solution containing its ions. In a galvanic cell, electricity is produced by the electrode potential of the two metal electrodes and their corresponding electrolytes.
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
Why electric field is negative gradient of electric potential?
This is because potential decreases if we move further from a positive plate
