A potential divider circuit is, essentially, a circuit where two or more components are arranged in series.
For non-physicists, these types of circuit can sometimes present problems, so in this post I am going to look in detail at the basic physics involved; and I am going to explain them using the CTM or Coulomb Train Model. (You can find the CTM model explained here.)
In the AQA GCSE Physics (and Combined Science) specifications, students are required to know that:
First, let’s look at the basics of describing electric circuits: current, potential difference and resistance.
1.0 Using the CTM to explain current, potential difference and resistance
Pupils tend to start with one concept for…
