Learn Electronics: The Resistor

Course Overview:

Do you know what you need to turn on a light, make a motor move, or create sound? All this and everything else in electronics is made possible with voltages and currents. If you set the right voltage on the wires of a motor it will move. If you set the correct current through a Light-Emitting Diode (LED) it will light up.

But how do you control voltage and current?

With the resistor.

That's what makes the resistor so interesting. When you understand how the values of the resistors in a circuit affects the voltage and the current, you'll have a new superpower.

In this course, you are going to get comfortable thinking about voltage, current, and resistance in circuits.

As you progress in electronics, you'll see that any component in a circuit can be thought of as a resistor in some way. Therefore, knowing how to work with resistors is crucial.

After finishing this course, you'll be able to look at simple circuit diagrams and see what the voltages and currents are. Which is exactly what you need in order to understand what a circuit diagram does.
