Unlike a series circuit, adding more components to a parallel circuit decreases the total resistance ® close resistance (R) How difficult it is for current to flow. of the circuit.

Series circuits and parallel circuits are both used a lot, ... And in an exam question, they might actually ask you to calculate or explain the resistance of something like a lamp.

Human conductivity, electrical resistance and series & parallel circuits! Human conductivity, electrical resistance, series & parallel circuits and more! The Curious Crew learns how all circuits ...

However, this is a great time to look at the difference between series and parallel circuits. ... Suppose each lightbulb has a resistance R (it doesn't matter than lightbulbs are non-ohmic).
