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 ...

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 ...

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 ...
