Basic Electricity: Parallel Circuits

Basic Electricity: Parallel Circuits One of the easiest ways I remember parallel circuits is: Parallel = same voltage, current divides, resistance gets smaller. That simple phrase covers the three big things you need to know for A&P basic electricity. A parallel circuit gives electricity more than one path to flow through. Each branch is connected across the same power source, so each branch receives the same voltage. 1. Voltage stays the same In a parallel circuit, each branch gets the same voltage as the source. ...

Basic Electricity: Series Circuits

Basic Electricity: Series Circuits One of the easiest ways I remember series circuits is: Series = same current, voltage divides, resistance adds. That simple phrase covers the three big things you need to know. A series circuit has only one path for current to flow. That is the key idea. Since there is only one path, the same current must pass through every component in the circuit. Think of it like water flowing through one single pipe. Everything in that pipe gets the same flow. ...
