Capacitors
If a resistor is like a cushion that is used to control the flow of electricity, then capacitors are like small rechargeable batteries that store small amounts of charge in them. Capacitors do two things at the same time:
- They allow AC, or Alternating Current, to flow through them.
- They resist the flow of DC, or Direct Current, through them.
By doing so, they are able to stabilize almost any circuit. There are two types of capacitors that are primarily used:
- Polarized capacitors – these have a positive and negative terminal
- Non-polarized capacitors – these do not have any positive or negative terminals
