The electric field exists if and only if there is a electric potential difference. If the charge is uniform at all points, however high the electric potential is, there will not be any electric field. Thus, the relation between electric field and electric potential can be generally expressed as ā āElectric field is the negative space derivative of ...

Electric Potential and Electric Field We have seen that the difference in electric potential between two arbitrary points in space is a function of the electric field which permeates space, but is independent of the test charge used to measure this difference. Let us investigate the relationship between electric potential and the electric field.

Electric potential energy is the energy that is needed to move a charge against an electric field. You need more energy to move a charge further in the electric field, but also more energy to move it through a stronger electric field.

The electric potential is the electric potential energy of a test charge divided by its charge for every location in space. Because it's derived from an energy, it's a scalar field. These two fields are related. The electric field and electric potential are related by a path integral that works for all sorts of situations.

The electrostatic potential8 V is de ned as the electric potential energy of the body divided by its charge: V = U=q. In terms of electrostatic potential, the work done by the electric eld is W= q V (5) where V = V nal V initial is the potential di erence9. The magnitude of the electric eld can also be determined from Eq. (3) and (5). E= V d cos( ) (6)

Figure 20ā3 The electric potential for a constant electric field The electric potential, V, decreases as one moves in the direction of the electric field. In the case shown here, the electric field is constant; as a result, the electric potential decreases uniformly with distance. We have arbitrarily set the potential equal to

We can think of electric potential energy as a field existing in the space around . Potential energy is a scalar quantity, so a potential energy field is a scalar field. It has a magnitude everywhere in space, but does not have direction. (Another example of a scalar field is the temperature everywhere in a room.)

Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Electric potential is measured in joules per coulomb (i.e., volts), and differences in potential are measured with a voltmeter.

The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field with negligible acceleration of the test charge to avoid producing kinetic energy or radiation by test charge.

It does not depend on the value of the potential itself. To illustrate this with a crude example, suppose the x component of electric field at a point has a value 5 N/C. This could've been created by a potential difference of 0.005 over a distance of 0.001 i.e. E x ā Ī V Ī x 5 = 0.005 0.001. Note that Ī V = 0.005.

As of September 2014, eight states still have electrocution available as an execution method, including Alabama, Arkansas, Florida, Kentucky, Oklahoma, South Carolina, Tennessee and Virginia. These states primarily use lethal injection for inmate executions, and the electric chair is used only at the convict's discretion in most jurisdictions.

Even a cordless electric shaver that will have a battery inside is permitted in both hand luggage and checked baggage.

### Do electric stoves use a lot of electricity?

Most electric ovens draw between 2,000 and 5,000 watts, with the average electric stove wattage coming in at around 3,000 watts. So how much energy does an electric stove use per hour? Assuming an electricity rate of 12 cents per kilowatt-hour (kWh), a 3000-watt oven will cost you about 36 cents per hour at high heat.

### Are electric toothbrushes allowed in carry on luggage?

You can bring an electric toothbrush on a plane in your carry-on bag. Itās not something the TSA worries about. The TSA is more worried about your toothpaste than your toothbrush which should be limited to 3.4 ounces! In fact, the best place to pack electric toothbrushes is in carry-on bags for three reasons.

The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point. For example, if you place a positive test charge in an electric field and the charge moves to the right, you know the direction of the electric field in that region points to the right.
