# Relationship between voltage and ampere

### How to Convert Watts to Amps Simplified -- Converting Amps to Watts the easy way

The relationship between voltage, current, and resistance is described by 20 ohms results in one half ampere of current flowing in the circuit. Volts and amperes are measures of electricity. A volt is the unit of electric potential difference, or the size of the force that sends the electrons through a circuit. Relationship and Difference Between Voltage, Current and . The unit of current is amps or amperage and 1 ampere =1 coulomb/second.

There is now a local "blockage" or narrowing of the pipe, per our water pipe analogy where the current experiences some resistance. This greatly reduces the current flowing in the circuit, so the energy in the battery is released more slowly. As the battery forces the current through the bulb, the battery's energy is released in the bulb in the form of light and heat.

In other words, the current carries stored energy from the battery to the bulb, where it is turned into light and heat energy. The image above shows a light bulb as the main cause of electrical resistance.

A watt is the base unit of power in electrical systems. It can also be used in mechanical systems.

It measures how much energy is released per second in a system. In our battery diagram, the size of both the voltage and the current in the bulb determine how much energy is released.

### What are volts and amperes?

In the diagram above, the light bulb would get brighter as the power, measured in watts, increases. We can calculate the power released in the bulb, and of the electrical system as a whole, by multiplying the voltage by the current.

So, to calculate watts, the following formula is used. How to Calculate with Watts, Amps, Volts, and Ohms If you want to do an electrical calculation involving voltage, current, resistance, or power, reference the formulae circle below.

For example, we can calculate the power in watts by referencing the yellow area in the circle. This formulae circle is very useful for many electrical engineering tasks.

This oscilloscope is used to visualize what is happening with the charge in a system.

## Convert Watts to Amps

All materials are made up from atoms, each atom consist of protons, neutrons and electrons. These three are together in the atom. But, if we separate them from each other they want to reform to exert a potential of attraction called a potential difference.

When we build a closed circuit, these electrons move and drift back to the protons because of their attraction to create a flow of electrons, this is called electric current.

The electrons do not flow freely due to the restriction of flow of electrons, this is called as resistance.

Then all basic circuits comprise of three separate quantities, namely voltage, current and resistance. Electrical Charge Electricity is the movement of electrons, it creates charge which we can connect to do the work, your light, phone, stereo, etc.

These all are operated using the basic power source that is, the movement of electrons. Current is the flow of electrons Resistance is defined as, it is the tendency of a material to restrict the flow of current.

So, when we discuss about these values, the behavior of electrons in a closed loop circuit allows charge to move from one place to another. He described a unit of resistance which is defined by voltage and current. The difference between voltage and current and resistance is discussed below.

In this equation, voltage is equal to the current and that is multiplied by resistance. Basic Circuit Diagram of V, I and R In the above circuit, when the voltage and resistance values are given, then we can calculate the amount of current.

The differences between V, I and R are discussed below. The voltage is defined as, it is the potential difference in charge between the two points on a circuit, it is also called electromotive force. One point has more charge than another. The unit volt is termed after invented by Italian physicist Alessandro Volta.

The term volt is represented by the letter V in schematics. The measuring instrument of voltage is the voltmeter. Voltage is the source and the current is its result, it can occur without current.
