When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.

National 4; Series and parallel circuits Current in parallel circuits. Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values.

The circuit’s main components comprise amplitude detector D 1, capacitor C 1, and Schmitt trigger Q 1 /Q 2 to control a current through the optocoupler’s LED. D 2 and D 3 stabilize the base voltage of ...

Fig. 1. Components of asymmetrical short circuit current waveform. Figure 1 (above) illustrates a typical short circuit current waveform for one phase of a 3-phase synchronous generator, previously ...

Other than the small current flowing in R 3 and R 4 and the current in D 2 ’s cathode, the circuit draws no current from the supply in its normal, untripped state. Related articles: Load switch with ...

Understanding the role of short-circuit current is critical to the reliability of your electrical system and to the safety of the people who maintain it. When designing or modifying a distribution ...
