100

This is the flow of electric charge through a conductor

What is current

100

A circuit must be this to allow current to flow.

What is closed (complete)

100

This component limits the flow of current.

What is a resistor

100

This tool is used to measure voltage, current, and resistance.

What is a multimeter

100

This experiment uses a lemon to generate electricity.

What is a lemon battery

200

This unit measures electrical current

What is the ampere (amp)

200

This component provides power in most beginner circuits.

What is a battery

200

This component emits light when current flows through it.

What is an LED (light-emitting diode)

200

This unit measures resistance.

What is the ohm (Ω)

200

This is the path electricity follows through components.

What is a circuit

300

This force pushes electrons through a circuit

What is voltage

300

This device opens and closes a circuit.

What is a switch

300

This component stores electrical energy temporarily.

What is a capacitor

300

This law relates voltage, current, and resistance.

What is Ohm’s Law

300

This component is often used to detect light levels.

What is a photoresistor (LDR)

400

This material allows electricity to flow easily

What is a conductor

400

A circuit with only one path for current is called this

What is a series circuit

400

This component allows current to flow in only one direction.

What is a diode

400

This tool helps connect components without soldering.

What is a breadboard

400

This project triggers sound when a magnet closes a switch.

What is a reed switch alarm

500

This material resists the flow of electricity

What is an insulator

500

A circuit with multiple paths for current is called this

What is a parallel circuit

500

This component can amplify signals or act as a switch.

What is a transistor

500

This setting on a multimeter measures electrical pressure.

What is voltage mode

500

This type of circuit makes an LED blink repeatedly.

What is an oscillator circuit
