Volts (V)
Definition: Volts measure electrical voltage, which is the force that "pushes" electrons through a circuit.
Common Analogies: Imagine voltage as the water pressure in a pipe. Higher pressure makes the water (electrons) flow faster.
Formula: V = I * R (Voltage = Current x Resistance)
Amperes (A)
Definition: Amperes measure electric current, which is the amount of electrons passing through a point in the circuit per second.
Common Analogies: Electric current is like the flow of water in a pipe. Greater flow means more water passing through a point.
Formula: I = V / R (Current = Voltage / Resistance)
Watts (W)
Definition: Watts measure electrical power, which is the rate of energy consumption.
Common Analogies: Electrical power is like the amount of work that water (electrons) can perform when passing through a point in a pipe.
Formula: W = V * I (Power = Voltage x Current)
Transcription:
This outlet here is for 127 volts. This circuit breaker here is 63 amperes. And this fan here needs 100 watts to work. All of this is related to electrical energy. Knowing these three parameters is fundamental for the proper use of equipment in your home. Today you're going to learn once and for all what a voltage, a battery, and an ampere are.
I'm going to ask permission from the more technical folks—chemists, physicists, mathematicians, engineers, and the like—because today's topic is simplification, and that's why I'm going to use a bottle, a disposable bottle, and a piece of hose to explain all this a little.
The word "electric" or "electricity" is directly linked to electrons, and it's precisely the movement of these electrons that makes all the electronic or electrical equipment in our house work. Let's imagine here, then, what the water inside this bottle is. That is, some electrons. When I open the tap, this water will come out with a pressure of 127 volts.
Now, when I increase the pressure here, it's due to gravity. I go from 127 volts to 220 volts. This means the pressure of the electrons here is much greater than this thinner hose, which is 10 amps. This thicker hose is 32 amps. This means the volume of electrons inside is much greater than that of a 10-amp hose.
We are already relating this to the thickness of the cables used in our installations. Finally, there's power, which is the amount of electrons needed for a device to function. This one, in this case, is 100 watts. A shower, for example, will consume much more watts, 6000 watts, which is how many electrons it needs to work.
In short, voltage is measured in volts and electron pressure in amperes. It's the volume of electrons, that is, the thickness of the power bar (watts) is how many electrons the device consumes to function. I hope you enjoyed it. Don't forget to leave a like.
