In this project, we’ll explore the differences between series and parallel circuits.  We’ll start with some vocabulary. 

series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor, but the voltage is not. 

parallel circuit is one in which the resistors are arranged in parallel, so that the current can flow along several paths.  In this case, the current varies, but the voltage across each resistor is the same. 

In this project, we’ll build each type of circuit and calculate the voltage and current within the circuit to see these differences.
