• an insulating component

What is an electrical insulator?

• is a material in which electric current does not flow freely

• is a material in which electric current partially flows

• is a material in which electric current flows freely

To connect an 3V LED lamp to a 9V battery I will need:

• a 9V Battery, wires and the LED

• A 9V Battery, wires, the LED and a resistor

• A 9V Battery, wires and a potentiometer

Jumper wires are simply wires that have ...

• connector pins at each end, allowing them to be used to connect three points to each other without soldering.

• connector pins at each end, allowing them to be used to connect two points to each other with soldering.

• connector pins at each end, allowing them to be used to glue two points to each other without soldering.

• connector pins at each end, allowing them to be used to connect two points to each other without soldering.

A resistor is...

• an insulating component component that opposes the flow of either direct or alternating current, employed to control the circuit

• a electrical component that opposes the flow of either direct or alternating current, employed to control the circuit

• electrical component that opposes the flow of either direct or alternating current, employed to close the circuit

• an insulating component component that opposes the flow of either direct or alternating current, employed to open and close the circuit

A common battery (3V, 9V or 1.5V) is...

• a device that stores chemical energy and converts it to electrical energy

• device that stores electrical energy and converts it to electrical energy

• a device that stores radioactive energy and converts it to electrical energy

• a device that stores sun energy and converts it to electrical energy
