CHAPTER 4
Some Basic Electronic Components
We will now look at two electronic components that are often used in electronics—resistors and capacitors.
Resistors pass electricity with varying amounts of conductivity. For example, a perfect wire has no resistance and has ideal conductivity of electricity. On the other hand, a thin wire has resistance and restricts the flow of the electrons somewhat. The higher resistance results in higher restriction of electron current flow. For example, a 10 million–ohm resistor reduces electron current flow to a “trickle,” but it can be useful in many circuits.
However, we will start first with capacitors since ...
