Previous tutorials have described that resistors may either be connected as a series circuit or a parallel circuit where the currents and voltages are obtained using Ohm’s Law. To produce more complex ...

Two lamps connected in series with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in series. If one lamp breaks, the other lamp will not light. The current is ...

a voltage divider reduces the voltage in a circuit the resistance value of the resistors will set the output voltage potential dividers can be two resistors connected in series across a circuit it is ...

A recently granted patent (Publication Number: US11758620B2) describes an electrical heating apparatus that includes a heat-emitting resistor, a control device for switching the resistor, and an ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
