ELECTRIC CIRCUITS
SHORT SUMMARY NOTES FOR BOTH GRADE 12 AND 11
ELECTRICAL COMPONENTS THAT MAKE UP AN ELECTRIC CIRCUIT
1. CELL/BATTERY
2. RESISTOR
3. LIGHT BULB
4. WIRE/CONDUCTOR
5. VOLTMETER
6. AMETER
7. SWITCH
PARALLEL AND SERIES CIRCUITS
PARALLEL CIRCUITS
. voltage is the same
. resistors are current dividers
. adding a resistor causes a decrease in the total resistance hence increase in total current
. more than one pathway for current to pass through
SERIES CIRCUITS
. current is the same
. resistors are voltage dividers
. adding a resistor causes an increase in the total resistance hence a decrease in total current
