Our last go-round inside a DC circuit! We’ll encounter junctions, loops, and capacitors! What happens when there are MULTIPLE batteries, connected in ‘parallel’? And what happens when we add ...

Of course, we all know that capacitors are conceptually two conductors separated by a dielectric of some sort. But outside of air-variable capacitors you normally don’t see them looking like that. For ...

Every year lakhs of students appear in the Joint entrance examination. 12 lakh students appear in JEE Main 2017. This number is increasing each year and with it the competition is also increasing. To ...

The new capacitor is much smaller than a conventional device. (Courtesy: Nanyang Technological University) Researchers in Singapore have developed a prototype polymer capacitor that can store much ...

Immediately after the capacitor is connected to the battery, the light bulb will glow as current flows through the light bulb and the capacitor is charging. After some time, the capacitor is fully ...

A large capacitor is charged by a 6 V battery or a 15 V DC power supply. When a copper rod is shorted across the terminals of the capacitor, a large spark is produced. The spark is obviously more ...

Back to the Future may have been right: The cars of tomorrow will be powered by capacitors (they will not, presumably, be able to time-travel). At least, that’s what Tesla CEO Elon Musk said at ...

Researchers in the US have made the first high-frequency AC “supercapacitors” containing graphene electrodes. The devices, which are much smaller than conventional capacitors, could be used in ...
