In this video, Jonny Nelson explains resistance. The current through a component depends on both the resistance of the component and the potential difference across the component.

In other words, with the perfect setup, you could put a digital panel meter that reads the voltage in the circuit, and read the resistance directly. Zeroing it out would require more effort to get ...

Secondly, in a series circuit, the total potential difference of the power supply is shared between all of the electrical components. And finally, the total resistance of all components in a ...

THE electrical resistance of wood increases very rapidly with decrease in moisture content (grams of water present per 100 grams dry weight), so that, if two probes about 2 cm. apart are driven ...

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...

Capacitors play three important roles in an electronic circuit: charging and discharging; maintaining the voltage at the same level; and removing noise. Diode The diode is a two-terminal electronic ...

Copper and silver inks make for good electrical circuits on stretchable films, and are even solderable, but increase resistance each time they are stretched. Recently, a team out of the University ...
