- It's well known that a capacitor blocks DC, but allows AC. This video explains the exact reason behind this phenomenon.

Best explanation on TH-cam. Informative, short , simple . 10/10
Formula: Xc=1/2 Pi fc....... as we know that DC signal has 0hz frequency if you substitute this value in reactance Xc formula we get ♾infinity so if the reactance is high then current doesnot pass through it. This is why dc is blocked by capacitor in which we can prove theoritically.
Then what if i connect capacitor in parallel to rectifer output circuit still does this apply in that case we won't be able to use capcitor in full bridge rectifiers....
Then why does capacitor allow current to pass through it while charging ?
Sir: You short video was EXTREMELY informative. Great things come in small packages. thank you.
missing enough things in capacitor AC behaviour bro but still all videos all are the best keep on in this way
What Cody said. Best explanation on TH-cam. Informative, short , simple . 10/10
Each phase of AC is actually DC; so what capacitors really block is anything above a certain capacitance. Still, effectively it blocks DC more than AC like the video states.
tysmm sir searching for this since so many days
Very underrated video. More thumbs up should give for this.
Great 👍 easy tp understand
Great clear and straight to the point explanation!
Great simple and crisp explanations 👍
Keep doing
Keep growing
Very good explanation
good explanation
BUT, the capacitor doesn't block DC during the charging process. in fact, when the charging process begins, the capacitor acts like a short. Isn't this correct??
As you said, the current decreases but still exists in part 2. If the source voltage is V = |sin(t)|, it is a DC current and what does the current perform in this case?
In a pulsating DC current, the capacitor filters out the ripples.
eficient explanation.
Correct
Fantastic explanation, but you could do with a better mic.
Very Good
Thank you so much, it makes sense for me now
Why does the capacitor discharge with decreasing voltage?
Because when voltage start decreasing capacitor act as power supply by supplyng the the current to the circuit by discharging itself
Because after capacitor gets somehwat charged,it's V is greater than the decreasing induced V due to ac so charge flows from higher to lower V
Nice work
Thanks a lot!
