Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

In this Python Physics lesson, we show you how to compute current in a charging RC circuit using Python simulations. Learn the step-by-step process to model the charging behavior of resistors and ...

Explore how brightness changes in a circuit with two bulbs and a capacitor in this hands-on physics tutorial! Learn how capacitors affect current flow, energy distribution, and bulb luminosity through ...

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
