Parallel Circuit Fundamentals: Voltage, Resistance, and Current Rules

Using the same resistor and inductor from the series example, we now arrange them in parallel to explore AC behavior. Parallel R‑L circuit. Because the source frequency and component values remain unchanged, the individual impedances stay the same. We start our analysis with the following known val

Now that we’ve seen how series and parallel AC circuit analysis is not fundamentally different than DC circuit analysis, it should come as no surprise that series-parallel analysis would be the same as well, just using complex numbers instead of a scalar to represent voltage, current, and imp

The principle that any periodic, non‑sinusoidal waveform can be decomposed into a set of sine waves of different frequencies is foundational in AC circuit analysis. When a circuit is driven by a waveform that is not a pure sine, the elements in the circuit respond as if a spectrum of frequency compo

What Is Runout in GD&T? In the world of small metal parts manufacturing, the Geometric Dimensioning and Tolerancing (GD&T) system uses a combination of symbols and GD&T tolerances to provide insights into how to produce the features that are essential to a part’s form and function.
