electroscope to test the sign of the charge of an object. If an unknown charge is brought near to a charged electroscope and the leaf diverges more, the unknown charge is similar to the charge on the electroscope. CHARGING AN INSULATED BODY A neutral1.
Electrolytic Capacitor – Working Principle & Its Applications
An electrolytic capacitor is a capacitor that to produce a higher capacitance than other capacitor types employs an electrolyte. A liquid or gel that has a lot of ions in it is an electrolyte. Since almost all electrolytic capacitors are polarised, the positive terminal''s voltage must always be higher than the negative terminal''s voltage. …
