Questions on general knowledge and topical trivia, plus a few jokes, every Thursday. How will you fare?

This insulating material is called the dielectric. When a potential difference or voltage (V, volts) is applied across the two plates, an amount of opposite and equal charge (Q, coulombs) is stored in ...

To put it in numerical terms, if a 0.1 farad capacitor has 12V across it, the charge is 1.2 coulombs. Suppose our input signal is 12V and we let the capacitor charge up to that value.

Charge is a property of a body which experiences a force in an electric field. Charge is measured in coulombs (C). Since electrons are so small and one electron will not have much of an effect ...

Monty's hypothesis was that merely by sitting on his chair, rubbing against mohair, and typing, the veep could be discharging a decent quantity of Coulombs into his keyboard. The veep scoffed at ...

Do you know what time it is? Chances are good that you used a computer or a cell phone to answer that question. The time on your phone is about as accurate as chronometry gets these days.
