Many of your projects require the use of passive electronic parts of various strengths in the circuit, so you may want to know what passive electronic parts do, how they work, and what happens if you leave them outside.

Let's start with some words:

Electricity is the flow of electrons, which are negatively charged particles.

Voltage is the difference in charge between two points in a circuit. Voltage is also the force of current.

An electric current measures the speed at which electrons flow.

A simple way to understand the difference between voltage and current is to consider the tank discharged through a hose connected to the bottom hole. Here, water acts like electricity. Voltage is the amount of water pressure, and current is the speed of water flow.

Resistance measures a material's ability to resist electrons flowing through it.

If the width of the bottom hose remains the same, the flow of water through the hose is fast by adding water to the tank. Similarly, adding multiple voltages to a circuit increases current.

However, if the hose is replaced with a smaller hose, the same water pressure will produce a slower flow. Hose size provides resistance and reduces current. Resistors in a circuit serve the same function, reducing current through the components they use.

How do passive electronic parts resist?

The passive electronic parts in the project are through-hole passive electronic parts material designed with two flexible ends for bending and inserting the breadboard. The core of the passive electronic parts manufacturer is formed by a spiral or spiral of conductive material wrapped around an insulating core. The material is very, very thin, which forces the current to slow down and provide resistance. To increase the amount of resistance, the number of rings in the helix can be increased.

What happens if I don't use a resistor?

If the current passing through the component is too large for the component to handle, it may overheat the component and may cause damage to the component, or it may cause damage to the microcontroller. If the proper resistance is not used, the LED will burn out quickly.

If you want to see the effect a passive electronic part material might have on the circuit, but instead of connecting the buzzer to the ground with a wire, use a passive electronic part. You will see that the reduced current will silence the buzzer.
