May 28 2014 · How transistors work is probably the hardest concept for you to understand as a beginner. At least it was for me. The problem is that almost everyone is trying to teach that a transistor is "a semiconductor device". And instead of just telling you what it does they explain that "it consists of n-doped and p-doped materials".

Resistor resistance ratings cannot be determined from the physical size of the resistor(s) in question although approximate power ratings can. The larger the resistor is the more power it can safely dissipate without suffering damage. Any device that performs some useful task with electric power is generally known as a load.

A variable resistor is very important. It allows you to build a circuit with some degree of control. For example a volume knob can be a variable resistor. It can act as a control on the amount of current flowing. Here is a picture of a variable resistor from a dimmer switch. A variable resistor works by adjusting the path that current has to flow.
