Electrical components

3. A circuit that generates a continuous, periodic signal, such as a sine wave. It is used in various applications, including generating radio signals.
6. A component that stores electrical energy in an electric field and releases it when needed. It is used for various purposes, including smoothing out voltage fluctuations.
7. A material that allows electrical current to flow easily. Copper and aluminum are common conductors.
11. A material that restricts or prevents the flow of electrical current. Rubber and plastic are examples of insulators.
13. An electromechanical switch that is controlled by an electrical current. Relays are often used to control high-power devices with low-power signals.
14. An electronic component that allows current to flow in one direction only. It is commonly used to convert alternating current (AC) to direct current (DC).
18. The flow of electric charge (typically electrons) in a circuit. It is measured in amperes (amps).
19. A semiconductor device that can amplify or switch electronic signals. Transistors are fundamental to modern electronics.

1. A device used to join two or more electrical conductors together, facilitating electrical connections.
2. The electrical potential difference that drives current flow in a circuit. It is measured in volts.
4. A semiconductor device that emits light when an electric current passes through it. LEDs are used for lighting and displays.
5. A device that stores electrical energy chemically and releases it as electrical current when connected to a circuit.
8. A unit of electrical resistance. Ohm's law relates voltage, current, and resistance in a circuit.
9. A device that limits or "resists" the flow of electrical current. It is often used to control the amount of current in a circuit.
10. A safety device that interrupts the flow of current in a circuit if it exceeds a safe level. Fuses protect against electrical overloads.
12. A device that can change the voltage of an alternating current (AC) signal. It is crucial for distributing electricity efficiently.
15. A coil of wire that resists changes in the flow of current. It is often used in filters and as a component in transformers.
16. A complete path for electrical current to flow. Electronic devices are made up of various circuits.
17. A device that converts alternating current (AC) into direct current (DC). It is often used in power supplies.
20. A device that opens or closes a circuit to control the flow of current. It can be used to turn devices on or off.
