Kirchhoff's Laws

First we tested Current and voltage for parallel and batteries in series. From this we were able to prove Kirchhoff's rules. But Before we started to measure we had to learn how to measure we were given ammeters and taught the notation for voltage(AC and DC), resistance (ohms) and Current (DCA amd ACA)

This is the derivation for Kirchhoff's rules in series and in parallel.

Next we were thought how to read resistors and how to calculate or see their uncertainty.

Here is an example problem using Kirchhoff's rules, things to keep in mind for Kirchhoff's rules are looking at the junctions (where wires meet) and to set you loops and current in a closed of circuit. It is also good to now that current our is the same as current going in for batteries.
