ELECTRICAL ENCYCLOPEDIA

Series and Parallel Resistors http://www.learnabout-electronics.org   IN SERIES, so that the same current flows through all the components but a different potential difference (voltage) can exist across each one. IN PARALLEL, so that the same potential difference (voltage) exists across all the components but each component may carry a different current. Series and Parallel Circuits http://en.wikipedia.org   As an example, consider a very simple circuit consisting of four light bulbs and one 6 V battery. If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel. If the four light bulbs are connected in series, there is same current through all of them, and the voltage drop is 1.5 V across each bulb, which may not be sufficient to make them glow. If the light...
