Workshop safety and Lab coats
Why Should We Wear Lab Coats?
- Lab coats are personal protective equipment and should be worn in the workshop when working with tools and electrical equipment to avoid scraps and cuts.
- Appropriate lab coats should be fully buttoned with sleeves rolled down. They should also be fire-resistant.
- In case of an accident, it is much faster and easier to remove a lab coat than street clothes to minimize skin contact with hazardous materials.
When to Wear Lab Coats
- Always wear lab coats when working in a workshop.
- always wear lab coats when working with tools and heavy equipment.
When NOT to Wear Lab Coats
- Don't wear lab coats in public places, such as offices, lunch rooms, lounge areas, or elsewhere outside the laboratory, as they can transfer hazardous materials and contaminate these areas.

Module 3 - Identification and specification of electrical components - Electrical workshop
Module 3:
Dear Students,
Below is the list of information you need to know from Module 3 of electrical workshop.
- 9 basic electrical components from Module 3
- lamp - light indicator
- motor - motion indicator
- buzzer - sound indicator
- resistor - limit the flow of current
- variable resistor - adjust or control the flow of current
- LDR - light dependent resistor - resistance changes with light intensity
- capacitor - used to store electrical charge
- inductor - used to store magnetic field
- diode - lets current flow in one direction only
- You should know the function and uses of all the electrical components
- Resistor color code
- BBROY from Great Britain has a Very Good Wife
- Capacitor color code, you should understand the 3 numbers written on capacitors and determine the value of the capacitors from there.
- End of chapter questions and answers.

Applications of Capacitors, Inductors and Diodes
Capacitors:
Capacitors are used for several purposes:- Timing - for example with a timer controlling the charging and discharging.
- Smoothing - for example in a power supply.
- Filtering - for example in the tone control of an audio system.
- Tuning - for example in a radio system.
- Storing energy - for example in a camera flash circuit.
Inductors:
- Traffic Light Sensors: to detect the car and change the signal from red to green.
- Flittering: to filter out noise in any voice signal.
Diodes:
- Light Emitting Diodes
- Rectifier Circuits
- Directing current in one direction only
- Vending Machines
