HEALTH AND SAFETY
Always have Overalls and safety boots
1. Always listen carefully to the teacher and follow instructions.
2. Do not run in the workshop, you could ‘bump’ into another pupil and cause an accident.
3. Know where the emergency stop buttons are positioned in the workshop. If you see an accident at the other side of the workshop you can use the emergency stop button to turn off all electrical power to machines.
4. Always wear an apron as it will protect your clothes and hold lose clothing such as ties in place.
5. Wear good strong shoes. training shoes are not suitable.
6. When attempting practical work all stools should be put away.
7. Bags should not be brought into a workshop as people can trip over them.
8. When learning how to use a machine, listen very carefully to all the instructions given by the teacher. Ask questions, especially if you do not fully understand.
9. Do not use a machine if you have not been shown how to operate it safely by the teacher.
10. Always be patient, never rush in the workshop.
11. Always use a guard when working on a machine.
12. Keep hands away from moving/rotating machinery.
13. Use hand tools carefully, keeping both hands behind the cutting edge.
14. Report any damage to machines/equipment as this could cause an accident.
Volt is practical unit of electromotive force and potential difference
Ampere is unit of current
Ohm is unit of resistance
Watt is practical unit of power
Farad is unit of capacitance
Hertz is unit of frequency
Conventional current flow is where the current flows from positive to negative
Electron current flow is where the current flows negative to positive
To calculate watts the formula is VOLTS x AMPS
To calculate resistance in a parallel circuit is R1 x R2 Divided by R1 + R2
To calculate resistance in series circuit you just add the resistance.
This is all the important things that i learned in my first week.
PLEASE COMMENT IF YOU NEED ME TO IMPROVE!!
Good answers.
