What zero potential means, roughly, is that the charges in your system have cancelled out. For example exactly half way (or otherwise equidistant from them) between two equal and oppositely charged point charges, potential is zero. Is potential zero if electric field is zero? If the electric field is zero,Read More →
Answer: According to Columb’s law, Electrical forces between charges depend upon Product of Magnitude of charges, distance between charges and permitivity of the medium where charges locate. How does force depend on intervening medium? The Coulomb Force between two charges decreases when a dielectric medium is placed in between theRead More →
For electrostatic paint to be applied, the vehicle needs to be grounded and positively charged. This creates a magnetic attraction to the negatively charged paint. Due to this charge, when the paint leaves the nozzle, it is attracted to the vehicle’s charge and will stick to it. How long doesRead More →
To recharge a mask, the group sandwiched it between two metal plate electrodes, then zapped the masks with an electric field strength of 800 volts per millimeter. The field needed to be high enough to cause the polypropylene mask fabric to become conductive so charges could be deposited on it,Read More →
A dry electrostatic precipitator (ESP) electrically charges the ash particles and imparts a strong electric field in the flue gas to collect and remove them. An ESP is comprised of a series of parallel, vertical metallic plates (collecting electrodes) forming lanes through which the flue gas passes. What companies useRead More →
Specifically, ESPs are used heavily in industries like petroleum processing, chemical processing, materials handling, textile, machining, electronics and general manufacturing. What are the two types of electrostatic precipitator? There are four basic types of ESPs: plate and wire (dry), flat plate (dry), wet, and two-stage. ESPs provide a large airRead More →
