Which of these items is needed to make the light bulb light up?
a conductor
an insulator
another power source
a piece of wood
Explanation
The answer is "a conductor."
Some types of matter transfer energy more easily than others. These substances are called “conductors.” An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. Some examples of conductors are copper, steel, gold, aluminum, and brass. If a substance does NOT transfer energy efficiently, it is called an insulator. Some common insulators are: Glass, Air, Plastic, Rubber, Porcelain, and Wood.
Jamal wants to make an electrical circuit, but he only has a power source and two wires that are not connected. Which of the following must Jamal also have to make an electrical circuit?
a conductor
an insulator
a battery
a rubber stopper
Explanation
Jamal would also need an electrical conductor to complete the circuit
