One of the most common questions I get asked is, “what is the electrical potential from the dot in the figure?” The answer is that we don’t know. We know that the potential is not the same thing as energy. It can be seen in a similar way as the difference between an electric current and thermal energy, but it is something we can’t really measure. This is something that we can do though. We can make a simple calculation.

The potential at the point indicated in the figure is the same as the potential at the centre of the circle. The negative charge that the dot represents is the same as the negative charge at the centre of the circle. So we can calculate the potential at the point indicated with the dot in the figure.

This is something you can do in a lab though. Take two point charges, that have the same magnitude, and put them side by side. Put a positive charge at the centre of the circle and a negative charge at the centre of the circle. Now put a positive charge at the centre of the circle and a negative charge at the centre of the circle. Both charges now have equal magnitude.

So the potential at the point indicated by the dot in the figure is the same as the sum of the two charges. We can also calculate it using the electrostatic formula. This is something you can do in a lab too. Put two point charges, equal magnitude, on a wire, and put a positive charge at the centre of the wire and a negative charge at the centre of the wire. Now you will have two points with the same magnitude on a wire.

The reason we calculate the electric potential with the dot in the figure is because the dot is actually a mathematical symbol used to represent the charge. In the electrostatic formula, the charge of a charge is the difference between the positive and negative charges, so the potential at the point indicated by the dot in the figure is actually the sum of the two charges. So, in essence, it looks like we’re going through the same process as the electrostatic formula in solving some problems.

Basically, the dot in the figure is a mathematical symbol representing the charge. You can also think of it as a particle, a quark or a lepton. We can find the charge by noting that the dot represents the difference between the positive and negative particles, and plugging in the number and solving for the potential. The figure has a charge of zero, so the potential at the point indicated by the dot is equal to zero because the charge of the dot is zero.

If you’re familiar with the physics of electricity, you can think of the potential as a measurement that represents a quantity of energy. For example, if you have a cell phone and plug in a charged dot, the dot will produce a voltage equal to the energy in the cell phone because the cell phone has a charge of zero.

Well, that is what the dot represented in the figure, but what you probably mean is that the potential is equal to the energy you put into the dot. If you put a 0 into a dot, you will get a zero potential, and if you put a 1 into a dot, you will get a positive potential.

The potential is defined as the energy associated with a charge, so if you are able to put a charge into a dot, then the potential of the dot will be equal to the charge. The other way to look at this is that energy is the capacity of a battery. A battery has a certain amount of energy in it, and the more energy that a battery has, the more energy it can store.

This is quite an important concept to understand if you want to determine how much power a device needs to function. For instance, if you plug a device into a wall socket, you can easily measure the voltage of the wall socket to determine how much power that device needs to run. But the same is not true for battery-powered devices.
