Resistors

If a wire is analogous to a water pipe, what does a resistor do?
If a wire is analogous to a water pipe, a resistor makes the pipe narrower and decreases the flow of current.

In the case of the water pipe analogy for wires, what does the water pressure represent?
In the case of the water pipe analogy for wires, the water pressure represents the voltage.

In the case of the water pipe analogy for wires, what does the water flow represent?
In the case of the water pipe analogy for wires, the water flow represents the current.

In what three ways do carbon film resistors cause resistance?
The three ways that carbon film resistors cause resistance include:

  1. The composition of the material.
  2. The thickness of the material.
  3. The spiral pattern.

Capacitors

What does a capacitor consist of in its most basic form?
In its most basic form, a capacitor consists of a layer of insulating material with a conductive surface on each side.
