Circuits

There are two different circuits we learned about this week in class. The first type is a series circuit. Basically this is a circuit that has only one path to take because the resistors are arranged in a chain like form. One characteristic of this circuit is that current is the same all the way through. Another thing that is special to this circuit is that the resistance can be found by simply just adding up all of the resistances.
An example of a series circuit includes a flashlight because the entire mechanism has only one circuit that makes it work. This is an image of my uncle's flashlight:

The switch, wires, and bulb are all together in one circuit making it a series circuit.

The second circuit that we learned about is a parallel circuit. In this type of circuit resistors are arranged with their heads together and their tails together. Unlike a series circuit a parallel circuit breaks up into different paths. One characteristic of this circuit is that voltage across the circuit remains the same. When calculating the resistance of a parallel circuit you must add all the resistor values in inverse then again inverse the answer.
