How Does Current Flow Through A Capacitor In An AC Circuit?

by

How Does Current Flow Through A Capacitor In An AC Circuit? The capacitor is connected directly across the AC supply voltage. As the supply voltage increases and decreases, the capacitor charges and discharges with respect to this change. A current will flow through the circuit, first in one direction, then in the other. What do

How Long Do Aluminum Electrolytic Capacitors Last? Today’s aluminum electrolytic capacitors have longer shelf life, usually around 2 years, as compared to their predecessors. For aluminum electrolytic capacitors, the changes in ESR, capacitance, and leakage current are caused by chemical reaction between the aluminum oxide film and the electrolyte. How many years do electrolytic capacitors
