We use DC voltages in an electrostatic precipitator (ESP) because it is necessary to induce a charge on the particulates, and then attract them to a plate by the use of an opposite charge. An AC source would be changing constantly. That would leave our particulates picking up "different charges" at different times as they pass the plates. Further, these particulates wouldn't be attracted to the plates because the plates would be changing polarity as well.
ESP's use a DC source to apply a charge of a given polarity to the particulates in the air stream, and use a plate of the opposite charge to attract and "hold" the particulates. AC sources can't do that.
What else can I help you with?
What is the voltage required for an electrostatic precipitator?
There is a lot of variation in the applied DC voltages that operate an electrostatic precipitator (ESP). Some work on a few thousand volts (a few kV), while big industrial units might run on upwards of 100,000 volts (100 kV).
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
How do you amplify DC voltage?
Either electronically through a DC Bus similar to what is used in a Variable Frequency Drive, or through a Voltage doubler where resistors in parallel with a series r off of the p resistor acts as a voltage multiplier. Search for Voltage divider, or DC amplifier.
What is meant by DC-DC luo converter?
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...

Is Electrostatic instruments measure ac and dc?
A DC voltmeter can read an electrostatic field's potential since it can measure a non-changing voltage. However, a electrostatic charge is by definition non-moving. When it does move, it becomes a direct current.
Why dc dc conversion is used?
To change the voltage.
What is the voltage used by processor?
5 voltage dc
What device used to increase or decrease DC voltage?
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
What is the principal component used to regulate the DC voltage in a DC power supply?
transistor
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
Does DC generator produce a smooth DC voltage output?
A DC generator typically produces a pulsating output voltage rather than a perfectly smooth DC voltage. This is due to the nature of its operation, where the generated voltage fluctuates with the rotation of the armature within the magnetic field. To achieve a smoother DC output, additional components such as filters or voltage regulators are often used to reduce the ripple and stabilize the voltage.
What are 4 types of DC voltage?
There is only 1 type of DC voltage, and that is direct current. In order to better answer your question, you need to be more specific.
How do you amplify DC voltage?
Either electronically through a DC Bus similar to what is used in a Variable Frequency Drive, or through a Voltage doubler where resistors in parallel with a series r off of the p resistor acts as a voltage multiplier. Search for Voltage divider, or DC amplifier.
How do rectifiers and transformers work in a PC power supply?
There is no transformer used in PC power supply. There is rectifier used to rectify or convert AC input voltage into DC output voltage.Transformer based rectifier produces some spikes at the output DC voltage, hencethey uses SMPS (Switch Mode Power Supply) to avoid spikes to the output DC voltage and get a smooth DC voltage.
What is used to provide the proper voltage to a CPU?
A power supply that transforms AC to DC is used to provide the proper voltage to a CPU.
