Learning Objective
I can analyze series and parallel circuits
- 1
In a series circuit, the current is the same through every component, and all components must be working for current to flow.
- 2
In a parallel circuit, the total current is the sum of the currents in each parallel pathway, and the voltage drop is the same along each pathway.
- 3
Adding more resistance in a series circuit will decrease the amount of current, resulting in dimmer light bulbs.
