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. then, place the number of the correct part next to the phrase that describes it. idaho instrument, inc. 9 a good test point reduces the number of wires, thus providing good serviceability for fuses and relays manually opens and closes circuits an electrically operated switch a solid - state relay a heavy - gauge wire placed in high - amperage circuits, protecting circuits from overloads - memo -

Explanation:

1. Connector (15): A good test point. Connectors are often used as test points in circuits.
2. Junction Block (13): Reduces the number of wires, thus providing good serviceability for fuses and relays. Junction blocks consolidate wire connections.
3. Switch (10): Manually opens and closes circuits. This is the basic function of a switch.
4. Relay (7): An electrically operated switch. Relays use an electromagnet to operate a switch.
5. Transistor (6): A solid - state relay. Transistors can act as electronic switches (solid - state relays).
6. Fusible link (4): A heavy - gauge wire placed in high - amperage circuits, protecting circuits from overloads. Fusible links are designed to melt (open the circuit) under excessive current.

Answer:

1. A good test point
2. Reduces the number of wires, thus providing good serviceability for fuses and relays
3. Manually opens and closes circuits
4. An electrically operated switch
5. A solid - state relay
