Voltage for Dummies

Voltage is a basic concept in the world of science and electricity. It is a term we use to describe the force or pressure that pushes electric charges, also known as electrons, through a circuit. Picture it like a water hose - the more pressure you have, the faster the water flows through. Voltage is like that pressure for electricity, pushing those electrons along a wire or through a device.

But why is voltage important? Imagine you have a circuit with a light bulb. In order for that bulb to light up and produce light, it needs a flow of electrons. Without voltage, there won't be enough push for those electrons to move, and the light bulb won't work.

So, we can think of voltage as a driving force for electricity. The amount of voltage present determines how much current flows through a circuit. Just like in our water hose analogy, when we increase the pressure, more water flows out. In the same way, when we increase the voltage, more current flows through the circuit.

Now let's talk a little bit more about how voltage works. Voltage is often measured in a unit called volts (V). It can be produced by different sources, like batteries or power outlets. These sources create an imbalance of electric charges, creating a potential difference between two points in a circuit. This potential difference, or voltage, is what causes the electrons to move.

But what happens if the voltage is too high or too low? Well, just like with our water hose, if the pressure is too high, it could damage the circuit or cause a device to malfunction. And if the pressure is too low, the electrons won't have enough push to move through the circuit, and again, the devices won't work.

So, to recap, voltage is the force or pressure that pushes electrons through a circuit. It is the driving force for electricity, providing energy for devices to function. It is measured in volts and can be too high or too low, affecting the performance of circuits and the devices connected to them.
