Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body. C = Q/V = ε A/d = ε0 εr A/d The ability of a capacitor to store maximum ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...

There was a recent news item regarding a teenager's project to use a super capacitor as a quick-charging energy storage device. The primary claim is that this could be used to fully charge a phone in ...

Part 2 goes further into the methods that can help lower EMI in switched-cap designs, including implementation of active EMI filters and visible light communication. Part 2 delves further into why ...

Ohmic resistors are generally employed to limit the current when charging capacitors. This, however, is accompanied by technical risks. If, for example, the capacitor short circuits or the relay has a ...

Battery technology is the talk of the town right now, as it’s the main bottleneck holding up progress on many facets of renewable energy. There are other technologies available for energy storage, ...

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 ...
