What else can I help you with?
Electric device blocks dc but allows ac?
A capacitor blocks DC but allows AC.
How capacitor bypass alternating current?
It passes AC through it and blocks DC
What is the use of coupling capacitor?
It allows AC current to go through, but blocks DC current.
How can a normal person understands a embedded programming?
Simply how capacitor blocks dc and allows ac after charging?
Does a charged capacitor block DC or AC or both?
It blocks DC or it wouldn't be charged. It passes AC through it to ground or it wouldn't filter. But in the early days charged electrolytic capacitors were used as rectifiers or AM detectors.
Why we use blocking and by pass capacitor in CE amplifier?
As the DC component in the signals are not required to be amplified, rather not required at times. Thus a blocking capacitor blocks this DC component from.entering the amplifier. Bypass capacitors are used at the emitter end so that the AC signal reaching the emitter end does not alter the biasing required to maintain the Q-point. All the above happens using the basic characteristic of a capacitor, that it blocks DC and passes AC.
Why a capacitor does not accept AC?
A capacitor conducts AC but do not conduct DC because it is meant to store charge.
Why capacitor does not store alternate current but store direct current?
Because Alternet current has both positive as well as negative cycle capacitor does not conduct for negative cycle of the Alternet current and DC all are positive cycle thats why it capacitor conduct for DC not for AC
Can we use AC capacitor in surge suppression circuit DC?
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
The electric device which blocks DC but allows AC is called?
A capacitor is a device which blocks DC, but allows AC. When a capacitor is completely charged it does not allow current to pass through it. Initially when capacitor starts charging it has maximum current which flows and voltage is minimum, during charging current decreases with time and voltage increases. When capacitor is completely charged, it has maximum voltage and minimum current. However the AC has both positive and negative half cycles, during positive half cycle capacitor starts charging but during negative half cycle it discharges, and hence it doesn't get fully charged at AC, and current always flows through it.
What devices can be used to block DC and pass AC?
simple capacitor can do this job (to block dc and pass ac).
What will happen if you changes the polarity of the capacitor in their respective position?
It will either explode right away, or work for a short time then explode. Note though, that the capacitor's polarity only applies to DC voltage. Because AC flows through a capacitor, if there is no DC offset, it matters not which way the capacitor goes.
