# Amp and voltage relationship

### How to Understand Electricity: Watts, Amps, Volts, and Ohms | Owlcation

In electrical engineering, there is a basic equation that explains how voltage, current and resistance relate. This equation, written below. Electronics Tutorial about the Relationship between Voltage Current and an electrical current of one ampere through a resistance of one Ohm. Voltages are. To put it simply, in a direct current electrical circuit or in an alternating current circuit with a purely resistive equivalent load, one watt (W) equals one volt (V).

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. 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.

To him work is required to move an object against a force that opposes its motion.

## QUICK TIP — What’s the difference between Amps, Volts and Watts?

So lifting your Hiwatt DR from the floor to your work bench requires work, because you are moving the amp upwards against the force of gravity that opposes it.

On the other hand, carrying a Twin Reverb around the block is no work at all, because the amp is moving horizontally - gravity does not oppose the movement in that direction. So when the road crew complains just refer back to this tutorial and explain to them why there is no work involved. Moving the amp from your test bench to the floor takes work, in this case negative work because the direction of motion is helped along by the force of gravity.

If all this sounds strange already, just add this concept to the mix: It takes a specific amount of work to lift your DR to the bench. It doesn't matter whether you jerk it upwards in a fraction of a second or take 20 minutes to lift it over the same path.

It is the same amount of work.

When the opposing force is measured in newtons and when the distance traveled against the opposing force is measured in meters, then the work, measured in joules, is the force times the distance: It turns out that a kilogram is a unit of mass.

The force that we think of when we try to lift that parallel push-pull boat anchor is the mass times the acceleration of gravity, which happens to be 9.

When we multiply the number of kilograms by 9. Problem The output transformer for your watt push-pull amp weighs 6. When holding it in your hands, what is the force of gravity pulling it downward?

The force of gravity in newtons is then 3kg 9. The top of your bench is 1. How much work is required to pick up the transformer and place it on the bench? 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. The voltage gets distributed over different electronic components which are connected in series in the circuit, and in parallel circuit voltage is same across all components which are connected in parallel.

### Relationship and Difference Between Voltage, Current and Resistance

The current is defined as it is the rate of flow of electric charge in a circuit. The measuring instrument of the current is an ammeter. The flow of current is same in all the components which are connected in series.

And, current gets distributed when components are connected in parallel. The Resistance is defined as, it is the opposition that a substance offers to the flow of electric current. It is denoted by the letter R. The unit of resistance is the ohm, and the measuring instrument of the resistance is a multimeter. Difference between Voltage, Current and Resistance When describing the differences between the voltage, resistance and current by taking a common analogy is a water tank.

Consider a water tank at a particular height from the ground. At the bottom of this water tank there is a tube.
