What else can I help you with?
Can a non polarized capacitor be connected to a direct current circuit?
Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
Is a cathode positive or negative in capacitor?
Depending on the capacitor we are using it will have a cathode.For example if we take a unicapacitor(it will allow current on both sides) it will have a negative and a bi capacitor it will not have negative
What current does a capacitor pass?
ac power (alternating current) it blocks dc power Many people will say a capacitor can't pass current because they consider Electric current to be the flow of electrons but that's not necessarily the case. In a capacitor current is passed by the building up and dropping of an electric field. DC does not flow for long of course.
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.
When capacitor is having an insulation how is it allowing ac current?
Capacitor does not allow any current through it.By the changing of electric field across the plates it is usually assumed that capacitor allow ac through it.Is it???
How does current flow in a capacitor?
Current does not flow through a capacitor in the same way as through a resistor. Instead, when a voltage is applied to a capacitor, it charges up by storing energy in an electric field between its plates. This stored energy can then be released when the capacitor discharges.
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
When a capacitor is being discharged in which direction does positive charge flow?
The 'conventional current' flows out of the positive side of the charged capacitor, and into the negative side. However, even though we never talk about it, we know that the things that actually carry the physical current around are the negatively charged electrons, and we know that when a capacitor is discharging, the electrons are flowing out of the negative side and into the positive side.
Which type of current capacitor can block and which type of current capacitor can store?
In an electronic circuit a capacitor can be used to block direct current. In general a capacitor stores electric charge. The charge in a capacitor is the voltage times the capacitance and that is also equal to the charging current times the time (all quantities in SI units - seconds, volts, amps, coulombs, farads)
What current exists in a capacitor when it is fully charged in an RC circuit?
When a capacitor is fully charged in an RC circuit, it holds a stored electrical charge. This charge creates an electric field between the capacitor plates, with no current flowing through the circuit at that moment.
What happens when a capacitor connected across a battery for a long time?
For a long time, The capacitor will be charged to the voltage of the DC battery, the positive side of the capacitor touching the positive terminal of the battery. Not much DC current will conduct, except for some tiny leakage current due to imperfection of the cap. The battery will be drained eventually.
