1) I don't even think about capacitors charging and discharging in AC circuits. The impedance of a capacitor at a certain frequency is important and is simple to calculate.walters said:Because AC currents have alot of different paths and AC currents are bi-directional and can reflect back to the input stages or around another path?
What is the Theory behind discharging currents and where do they go which paths?
Buy a multimeter, and experiment with it.So what test meter would tell what direction Current is flowing in ?
you can tell by the display. Ifyou see a -ve sign, it is flowing the wrong way. but, I was taught that current flowed from -ve to +ve. so how could it be bi-directional?how do i know which way current is flowing?
It's better to understand it by looking at polarities. for example, the anode of an LED should go to +ve, and the cathode to -ve through a resistor.i want to know how the circuit work you have to understand the AC current polaritys, path ways, discharging bi-directional to know how electronic preamps,mixers,power amps etc work and how to read a schematic more in detail how the AC currrent go

Wrong! Many circuits use a dual supply with negative voltages and currents.mstechca said:you can tell by the display. Ifyou see a -ve sign, it is flowing the wrong way.
Why? Looking at charging and discharging currents and their directions is pointless. The only parts in a circuit that have charging and discharging currents are capacitors:walters said:Can someone please look at the schematics i posted on the hyperlinks and take a Red pen and draw "Arrows" showing me where the currents directions are and take a Blue pen and show me the Discharging currents please just have a bunch of Red and Blue arrows showing me the directions of the currents please
