There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...

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 ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Supercapacitor technology often looks like a revolutionary energy storage technology on the surface, but the actual performance numbers can be rather uninspiring. However, for rapid and repeated ...

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, ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

As engineering innovations continue to advance ultracapacitors, their enhanced performance capabilities are expected to hasten the convergence of batteries and ultracapacitors—strengthening the ...
