battery
motor
switch
relay
junction block
circuit breaker
fuse
transistor
diode
ground
capacitor
connector
lamp
fusible link
then, place the number of the correct part next to the phrase that describes it.
allows current to flow in only one direction
changes electrical energy into mechanical energy
stores chemical energy and converts it into electrical energy
changes electrical energy into heat and light
stores electrical current temporarily
a reusable fuse - opens with too much current
reduces voltage to a specific level
provides a current return path
a thin metal strip which melts to protect circuits from overloads

Explanation:

• Resistor: Symbol 9. Resistors are components that oppose the flow of electric current.
• Switch: Symbol 10. Switches are used to open or close an electrical circuit.
• Circuit Breaker: Symbol 11. Circuit breakers are reusable fuses that open when there is too much current.
• Diode: Symbol 3. Diodes allow current to flow in only one direction.
• Connector: Symbol 14. Connectors are used to join electrical wires.
• Battery: Symbol 12. Batteries store chemical energy and convert it into electrical energy.
• Relay: Symbol 8. Relays are electromagnetic switches.
• Fuse: Symbol 4. Fuses are thin metal strips that melt to protect circuits from overloads.
• Ground: Symbol 5. Ground provides a current return path.
• Lamp: Symbol 1. Lamps change electrical energy into heat and light.
• Motor: Symbol 13. Motors change electrical energy into mechanical energy.
• Junction Block: Symbol 15. Junction blocks are used to connect multiple electrical wires.
• Transistor: Symbol 6. Transistors can amplify or switch electronic signals.
• Capacitor: Symbol 2. Capacitors store electrical current temporarily.
• Fusible link: Symbol 7. Fusible links are similar to fuses but are used in higher - current applications.
