In this week’s Gizmodo University: Discover Electronics, we’re diving headfirst into the principle theories of electronics. The second of four classes in this series, “Volts, Amps, and Ohms” is ...

It is hard to get very far into electronics without knowing Ohm’s law. Named after [Georg Ohm] it describes current and voltage relationships in linear circuits. However, there are two laws that are ...

Voltage and Current divider arrangements are the common in electronic circuits. Before selecting the value of resistors, it is necessary to calculate the voltage and current from the output of a ...

Because of the shell arrangements of electrons in various atoms and molecules, some substances are quite good at allowing a few electrons to move about freely (e.g., copper, silver, gold, aluminum), ...
