Background:
Another name for I/V characteristics is current-voltage. Current and voltage are the factors that are being investigated, there characteristics and effects in diodes of different colours. The Current or I in I/V characteristics refers to the flow of an electric charge. It is often carried out by electrons when moving through wires
Materials:
-green, red, blue, yellow coloured diodes
-breadboard
-wires
- 2X multimeters, 1 as a voltmeter and other as ammeter
-power supply pack
- Potentiometer
-470 ohm resistor
Method:
1. Attach power supply pack to mains power point
2. Adjust the power pack supply to four volts
3. Attach wire from positive terminal to potentiometer
4. Place a potentiometer to …show more content…
Turn on power supply and adjust the voltage across the LED using potentiometer
9. Increase voltage from 0 volts in 0.2 volt increment until 4 volts is reached
10. With each increment record amps in circuit
Risk assessment:
RISK
Identify the relevant risk/s or include any other relevant risks. RISK MANAGEMENT
Identify the relevant risk control measures that will be employed.
inhalation of dust Personal Protective Equipment:
inhalation of vapours □ Safety glasses/goggles
discomfort or irritation to eyes / skin / respiratory system □ Gloves
micro-organisms □ Lab coats
serious damage to eyes Ventilation:
ingestion of a toxic substance / harmful substance □ Windows
□ burns - chemical □ Fans
□ burns - hot naked flame / Bunsen burner when packing up / hot equipment / hot liquids □ Fume Cupboards
flammable substances Waste disposal:
stains to skin and clothing □ Laboratory bin/sink
substance toxic to aquatic organisms □ Waste container (return prep-room)
cuts - sharp edges / broken glassware / scalpel or blade Procedural:
fragile equipment □ Wash hands when finished
mains voltage power source □ Clean bench and work area
moving parts □ Safety and operational procedures
Risk Level:
