Please check back for opening updates. It was previously an event in , , , and , when it was called Shock Value in Division B. NFPA provides a wealth of safety information to help ensure the holiday season is a safe one. These two speakers are very similar in basic design philosophy, though their execution is quite different, mainly due to a decade's worth of improvements in dynamic driver technology. Do you still get child benefit on universal credit.

## What is a Series-Parallel Circuit?

Circuits consisting of just one battery and one load resistance are very simple to analyze, but they are not often found in practical applications. Usually, we find circuits where more than two components are connected together. There are two basic ways in which to connect more than two circuit components: series and parallel. 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.

They serve only to identify one resistor from another. The defining characteristic of a series circuit is that there is only one path for current to flow. In this circuit, the current flows in a clockwise direction, from point 1 to point 2 to point 3 to point 4 and back around to 1. Again, we have three resistors, but this time they form more than one continuous path for current to flow.

Each individual path through R 1 , R 2 , and R 3 is called a branch. The defining characteristic of a parallel circuit is that all components are connected between the same set of electrically common points. Looking at the schematic diagram, we see that points 1, 2, 3, and 4 are all electrically common. So are points 8, 7, 6, and 5. Note that all resistors, as well as the battery, are connected between these two sets of points.

We can have circuits that are a combination of series and parallel, too. In this circuit, we have two loops for the current to flow through: one from 1 to 2 to 5 to 6 and back to 1 again, and another from 1 to 2 to 3 to 4 to 5 to 6 and back to 1 again. Notice how both current paths pass through R 1 from point 1 to point 2.

This is just a preview of things to come. You can jump straight to the next pages on series circuits and parallel circuits or to What Is a Series-Parallel Circuit? In a purely parallel circuit, there are never more than two sets of electrically common points, no matter how many components are connected.

There are many paths for current flow, but only one voltage across all components:. Series and parallel resistor configurations have very different electrical properties.

For series circuits, voltage gets dropped at each component, but the current is same for all of them, as the path is continuous. So, series circuits are also called Voltage dividers. For that very behaviour, these circuits are also called as Current dividers.

Series Configuration Circuit First, an example of a series circuit: 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. Series-Parallel Configuration Circuit In this circuit, we have two loops for the current to flow through: one from 1 to 2 to 5 to 6 and back to 1 again, and another from 1 to 2 to 3 to 4 to 5 to 6 and back to 1 again.

There are many paths for current flow, but only one voltage across all components: Series and parallel resistor configurations have very different electrical properties. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points. Passive, Active, and Electromechanical Components.

Exploring the similarities and differences between the two types of electrical circuits. After learning how to build series and parallel circuits, your students will use ammeters and voltmeters to compare voltage and current flow so they can understand the similarities and differences between the two types of electrical circuits. Demonstrate for your students how an ammeter needs to be connected in the path of the moving electrons, so it becomes part of the circuit. Also demonstrate how the voltmeter must be connected in parallel to the dry cell or the light bulb as the voltmeter creates a second pathway for the current to flow. Put your students into groups and have them follow the instructions on their worksheets to build series and parallel circuits.
