Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum voltage ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

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 ...
