How ac voltage is superimposed on dc voltage?
AC voltage can be superimposed on DC voltage by adding the AC signal to the DC level in a circuit. This is often achieved using capacitive or resistive coupling, where the AC waveform rides on top of the constant DC voltage. The resulting waveform is a combination of the steady DC component and the fluctuating AC component, allowing for the transmission of both types of signals simultaneously. This technique is commonly used in various electronic applications, such as in modulation and signal processing.
Does a Cpacitor allow ac to pass through it?
no capacitor does not allow ac component .if allow then inductor allow dc component .
Does a pulsating DC contains ac components?
A: As a DC source change state rapidly this variation is consider an AC component
Why dc components operate at low voltage compared to ac component?
Because equipment operating on DC is usually low-power electronic equipment, and it uses a power-supply to convert the house AC supply to DC at the right voltage. Most appliances needing high power are designed to run on AC because that is the normal supply to houses.
Characteristics of a capacitor?
Block DC components and pass AC component
What component converts AC into clean DC power?
By using rectification we can convert the AC into DC....

How does a DC brushless motor work?
To state it simply, a DC brushless motor is not a DC motor. It is an AC motor with an inverter (or electronic commutator) on the front end to make the AC, so you can use a DC input.
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
What is an ac transistors?
As far as I know, transistors - and other electronic devices - basically work with DC, not AC. If a computer (for example) is plugged into an AC outlet, some device within the computer must first convert the AC current into DC current, which is then fed to the electronic components.

Why you use filters in your circuit?
we generally use filters to smooth the sharp curves of DC component we get when we rectify AC components the pulsating Dc is not desirable to a no. of devices. These filters are used to make the pulsating DC to a stable one . To be more clear a pulsating DC is viewed as a sum of DC component and AC component these filters actually block the AC components and retain the DC component . so, mainly capacitors and inductors are used to obstruct or pass the dc components respectively
Why not you use ac instead of dc to electronic components?
AC is easier and cheaper to send from the generators to the consumers than DC is.
Can DC series motor work on ac and DC and why?
A dc series motor can work on dc and ac because dc motors are totally reversible.
Why dc components operate at low voltage compared to ac component?
Because equipment operating on DC is usually low-power electronic equipment, and it uses a power-supply to convert the house AC supply to DC at the right voltage. Most appliances needing high power are designed to run on AC because that is the normal supply to houses.
Which is more useful ac aor dc?
AC and DC current both have useful advantages, depending on what you what to do with it.AC is more useful for sending long distance over transmission lines, as AC can be put through a transformer to change the voltage easily.All electronic devices work using DC only. Batteries provide DC and are readily available or can be created. All electronic devices, when used on a domestic AC supply, have their power converted from AC to DC, either within the device or an external power supply.More devices use DC than AC, but we could not get the power to where it is needed without AC transmission lines. Heavy motors were more efficient when constructed for AC supplies, but these days DC stepper motors are taking over, using electronic control circuits.
