This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

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.

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 ...
