Identify

Resistor (R)

Resistor purpose:

Limits the flow of electricity in a circuit.

Types of Resistors

Variable, Fixed Value

Identify

Fuse (F)

Fuse Purpose

Opens a circuit to stop a current if it exceeds a certain value

Types of fuses

Standard, Time delay, Fast acting

Circuit Breaker

an automatic device for stopping the flow of current in an electric circuit in case of excessive current.

Identify

Circuit Breaker (CB)

Trip Free vs Non-Trip Free Circuit Breakers

Trip Free is automatic, non-trip free can be manually set to not trip

Identify

Switch (S)

Switch

Device that either opens, closes, or changes a circuit

Define Poles, Throws, Breaks, + Positions

Poles: Number of terminals that currents can enter

Throws: number of circuits that can be controlled by each pole

Breaks: number of places that the switch opens/breaks the circuit

Positions: physical positions (I.E. on/off)

name some manual and automatic switch types

Manual: Toggle, Push button, multiposition

Automatic: mechanically acuted, pressure activated, thermal activated, proximity

Identify

Capacitor (C)

Capacitor

Component that stores and releases electrical energy by accumulating it on 2 plates

Identify 🥀

Lamp (DS)

Identify

Relay (K)

Relay

A device that uses an electrical signal to engage or break another circuit.

Components of a relay

Coil

Moveable contact

Fixed contact
