Question

1. circuits are drawn using various symbols that represent electrical components and wires. identify the various symbols used on wiring diagrams. identify the numbered electrical symbols by placing the correct number next to the part name below. resistor 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 overibads

Explanation:

• Resistor: Represented by a zig - zag line (symbol 9).
• Battery: Usually shown with two or more parallel lines of different lengths (symbol 12).
• Motor: Often has a circle with an 'M' inside (symbol 13).
• Switch: A simple line that can be opened or closed (symbol 10).
• Relay: Has a coil and contacts (symbol 8).
• Junction Block: A symbol that represents a connection point (symbol 15).
• Circuit Breaker: A symbol that can open the circuit (symbol 11).
• Fuse: A symbol that is like a small rectangle (symbol 4).
• Transistor: Has a specific three - terminal symbol (symbol 6).
• Diode: Allows current in one direction (symbol 3).
• Ground: A symbol that provides a return path (symbol 5).
• Capacitor: Two parallel lines (symbol 2).
• Connector: A symbol that connects wires (symbol 14).
• Lamp: A symbol that emits light (symbol 1).
• Fusible link: A symbol that can melt (symbol 7).

For the descriptions:

• Allows current to flow in only one direction: Diode (symbol 3).
• Changes electrical energy into mechanical energy: Motor (symbol 13).
• Stores chemical energy and converts it into electrical energy: Battery (symbol 12).
• Changes electrical energy into heat and light: Lamp (symbol 1).
• Stores electrical current temporarily: Capacitor (symbol 2).
• A reusable fuse — opens with too much current: Circuit Breaker (symbol 11).
• Reduces voltage to a specific level: Resistor (symbol 9).
• Provides a current return path: Ground (symbol 5).
• A thin metal strip which melts to protect circuits from overloads: Fuse (symbol 4).

Answer:

Resistor: 9, Battery: 12, Motor: 13, Switch: 10, Relay: 8, Junction Block: 15, Circuit Breaker: 11, Fuse: 4, Transistor: 6, Diode: 3, Ground: 5, Capacitor: 2, Connector: 14, Lamp: 1, Fusible link: 7.

Allows current to flow in only one direction: 3, Changes electrical energy into mechanical energy: 13, Stores chemical energy and converts it into electrical energy: 12, Changes electrical energy into heat and light: 1, Stores electrical current temporarily: 2, A reusable fuse — opens with too much current: 11, Reduces voltage to a specific level: 9, Provides a current return path: 5, A thin metal strip which melts to protect circuits from overloads: 4.
