3/10/2023 0 Comments Parallel vs series circuitFrom the positive battery terminal, current first encounters R 1. In the next picture, we again see three resistors and a battery. Series and Parallel Circuits Working Togetherįrom there we can mix and match. ![]() Where series components all have equal currents running through them, parallel components all have the same voltage drop across them - series:current::parallel:voltage. There are three distinct paths that current can take before returning to the battery, and the associated resistors are said to be in parallel. The other ends of these resistors are similarly tied together, and then tied back to the negative terminal of the battery. The node that connects the battery to R 1 is also connected to the other resistors. Voltage, Current, Resistance, and Ohm's Lawįrom the positive battery terminal, current flows to R 1.You may want to visit these tutorials on the basic components before diving into building the circuits in this tutorial. How a voltage source will act upon passive components in these configurations.How passive components act in these configurations.What series and parallel circuit configurations look like.We’ll then explore what happens in series and parallel circuits when you combine different types of components, such as capacitors and inductors. In this tutorial, we’ll first discuss the difference between series circuits and parallel circuits, using circuits containing the most basic of components - resistors and batteries - to show the difference between the two configurations. Where's the current going? What's the voltage doing? Can this be simplified for easier understanding? Fear not, intrepid reader. But, things can get sticky when other components come to the party. This is just a preview of things to come.Simple circuits (ones with only a few components) are usually fairly straightforward for beginners to understand. In this configuration, we’d say that R 2 and R 3 are in parallel with each other, while R 1 is in series with the parallel combination of R 2 and R 3. Notice how both current paths go through R 1(from point 2 to point 1). ![]() In this circuit, we have two loops for electrons to flow through: one from 6 to 5 to 2 to 1 and back to 6 again, and another from 6 to 5 to 4 to 3 to 2 to 1 and back to 6 again. Note that all resistors as well as the battery are connected between these two sets of points.Īnd, of course, the complexity doesn’t stop at simple series and parallel either! We can have circuits that are a combination of series and parallel, too: Looking at the schematic diagram, we see that points 1, 2, 3, and 4 are all electrically common. The defining characteristic of a parallel circuit is that all components are connected between the same set of electrically common points. Each individual path (through R 1, R 2, and R 3) is called a branch. ![]() And then there’s a third path from 8 to 7 to 6 to 5 to 4 to 3 to 2 to 1 and back to 8 again. There’s another from 8 to 7 to 6 to 3 to 2 to 1 and back to 8 again. ![]() There’s one path from 8 to 7 to 2 to 1 and back to 8 again. Now, let’s look at the other type of circuit, a parallel configuration:Īgain, we have three resistors, but this time they form more than one continuous path for electrons to flow. In this circuit the electrons flow in a counter-clockwise direction, from point 4 to point 3 to point 2 to point 1 and back around to 4. They serve only to identify one resistor from another.) The defining characteristic of a series circuit is that there is only one path for electrons to flow. (It should be noted that the subscript labeling-those little numbers to the lower-right of the letter “R”-are unrelated to the resistor values in ohms. Here, we have three resistors (labeled R 1, R 2, and R 3), connected in a long chain from one terminal of the battery to the other. There are two basic ways in which to connect more than two circuit components: series and parallel.
