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 ...

How do multiple capacitors behave as a single equivalent capacitor? ⚡ This video explains how to find equivalent capacitance using fundamental physics, covering series and parallel combinations and ...

Dielectrics are of two types: (i) Non-Polar Dielectrics: When the centre of positive charge coincides with the centre of negative charge in a molecule, e.g., Nitrogen, Oxygen, CO 2 etc. (ii) Polar ...

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 ...

How do those defibrillators you see on TV actually work? Surprise! Physics can explain! So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, ...

This video explains the physics behind reversed resistor and capacitor equations. We clarify why voltage–current relationships appear inverted in different contexts, connect the math to physical ...

The capacitance of a classical conductor is determined solely by its geometry. When charged, the electrons distribute in space in a manner that minimizes their electrostatic energy. Quantum mechanics ...

Ferroelectric materials, which were discovered nearly a hundred years ago, and have led to a huge range of applications, including digital information storage and neuromorphic computing, are still not ...

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 ...

If a larger value of resistance were used with the same value of capacitance in the above circuit, then a smaller current would flow, therefore it would take longer for the capacitor to charge up and ...
