Electrolytic Capacitor types/ uses?
About electrolytic (aluminium) capacitors..... what do the low ESR ones do that normal ones don't? And how come they have these capacitors in bipolar types, but not all are bipolar? Is it because of the size/cost? And lastly, can you make an LC circuit with any electrolytic capacitor?
P.S: In which frequency range are LC resonant ciruits best used? Cos I heard that lower/higher than a specific point, they become impractical or something....
