A route for the flow of electricity that has elements of both parallel and series circuits.

Combination Circuits:. A route for the flow of electricity that has elements of both parallel and series circuits. Example: find the current in each resistor . The first step is to simplify the circuit by making the parallel resistors into a single resistance.

Resistance

Resistance. What is a resistor?. A resistor is an object that slows down the flow of electrons and changes electrical energy into a different form Imagine construction on the highway forcing all the cars into one lane The construction is the resistor and the cars are electrons.
