Resistors in Series & Parallel
Resistors in Series
- When two or more components are connected in series:
- The combined resistance of the components is equal to the sum of individual resistances
Combined Resistance in Series
When several components are connected in series, their combined resistance is equal to the sum of their individual resistances
Resistors in Parallel
- When resistors are connected in parallel, the combined resistance decreases and is less than the resistance of any of the individual components
- If two resistors of equal resistance are connected in parallel, then the combined resistance will halve
Combined Resistance in Parallel
The above resistors will have a combined resistance of 2 Ω − half the value of each resistor
