• In electronic circuits the two values can be represented by e.g., – High voltage for a 1 – Low voltage for a 0 • Note that since only 2 voltage levels are used, the circuits have greater immunity to electrical noise the series portion of the circuit and then splits to flow through the parallel branches of the circuit. Some components are wired in series, others in parallel. Most automotive circuits are series-parallel, and the same relationship between voltage, current, and resistance exists. Use of Ohm's Law Applying Ohm's Law to series-parallel circuits is a
