In this exercise you will learn how use Geogebra to solve circuit problems using Kirchoff"s laws. The solutions will also be checked using the PhET circuit simulator.Consider the following circuit:The problem here is to find the current through each resistor. So that we can write equations for the circuit we first need to label the currents. These are often labeled I1, I2 etc. but here we will use a,b and c since this...
