Resistor

What is the main function of a resistor in a circuit?

• To generate electricity

• To store electrical energy

• To resist the current and cause a voltage drop

• To increase the current

What is important to remember about electrical components?

• Each has its own resistance

• They have no resistance

• They can only carry small currents

• They are all made of ceramic

What material is commonly used in resistors that carry large currents?

• Plastic

• Glass

• Copper wire

• High resistance wire

How is resistance measured?

• In volts

• In watts

• In amperes

• In ohms

Why do resistors have a wattage rating?

• To show how much light they emit

• To indicate their size

• To show how much heat they can handle

• To indicate their color
