To find the voltage and current through each resistor in a circuit, it first needs to be reduced to s single resistor. Click here if you do not know how to do this.
This 5 minutes YouTube video, http://www.youtube.com/watch?v=EpXikEJ818k, shows how to calculate the current through and the voltage dropped by each resistor in a simple, single battery, circuit. Below is a second video showing you how to check your work along the way, http://www.youtube.com/watch?v=x9Np8zKF124
Below is an image of what you page should look like when you are done with the example in the video.
