Explore the relationship between multiple resistors connected in parallel. Learn how connecting resistors in parallel affects their combined resistance and power rating.
- [Instructor] Resistors are connected in parallel…when both of their terminals are connected…to each terminal of another resistor as shown here.…The combined total resistance of parallel resistors…will be less than the resistance…of any individual resistor…because the parallel configuration…provides more possible paths…for electrons to take as they travel through this circuit.…When thinking about why combining resistors…in parallel affects resistance,…I like to use the analogy…of current passing through a resistor…being like cars traveling down a road.…
Adding a second resistor in parallel…creates a second possible path for the cars…to travel down.…The resistance along each path…corresponds to how difficult it is…for the cars to drive along it.…With a larger resistance…representing a more treacherous road.…If both roads have the same resistance,…the current traveling through them…will be split equally among each path,…half of the drivers will choose…to go down the left side…and half will choose to go down the right side.…
