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 ...

Electrostatic Potential and Capacitance Formula Sheet Class 12: In this article, students can find Class 12 Physics Chapter 2 Electrostatic Potential and Capacitance all formulas along with a PDF ...

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 ...

A research team led by Prof. MENG Guowen from the Institute Solid State Physics, Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS), cooperating with Prof. WEI Bingqing ...

"Supercapacitors" take the energy-storing abilities of capacitors (which store electrical charge that can be quickly dumped to power devices) a step further, storing a far greater charge in a much ...

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 ...
