Sometimes, it's the little things that are just so darn handy to have around. I'm often confronted with having to choose a parallel pair of resistors to get as close as possible to some non-standard ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...

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 ...

When both terminals of resistors are respectively connected to each terminal of the other resistor or resistors, they are said to be connected in parallel. Resistors can be connected such that they ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...
