How Resistors Work

How Resistors Work

• Resistors are made in various shapes, sizes, resistance values (in ohms)  and wattage ratings.
• Resistors are used as current-limiting devices and an electronic circuit will not work without them.
• The value in ohms of a resistor is what will determine the electron current.
• A low resistance will cause a large current to flow, and a high resistance will cause a small current flow.
