Full page Black and White on negative Series, PaXattat, & Combination Circuits The best way to get a grip on what is actually happening in any electrical circuit is to understand the relationships between Volts, Amps, and Ohms in Ohm's law. Let's explore how these relationships change depending on the layout of the circuit and its components. A circuit is considered to be in series when all components are connected in such a way that there is only one possible path for current to flow. This...
