Charge
• Charge = Current x time (Q=It)
Voltage
• Voltage = Current x Resistance (V=IR - also known as Ohms Law)
Circuit types
parallel and series
Circuit Current, Voltage and Resistance rules
o Series - Current same, voltage shared, add resistance to get total resistance o Parallel - Voltage same current shared in branches of circuit
Light bulb
• Light bulb - effects of heat on resistance (non-ohmic graph of V against I is not straight line)
Special resistors
- LDR, thermistor and diode ,Graph shapes and uses
- Alternating and Direct Current
o Graphs of wave forms and sources
- Domestic Electricity Supply
o Plugs and wiring (Blue Neutral, Brown Live, Green and Yellow Earth) ♣ Common Faults o Protection by Earth wire, fuses and double insulation
