brush discharge การใช้

Most are systems of points designed to produce brush discharges.
Other forms of ESD include corona discharge from sharp electrodes and brush discharge from blunt electrodes.
To apply brush discharges ( called " " effluves " " ) to the outside of the patient's body, electrodes consisting of one or more metal points on an insulating handle were used.
Because the electric field decreases as the distance from the conductor increases, it eventually drops below the value needed for ionization, so corona and brush discharges have a limited extent and are localized near the conductor.
On 26 August 1883, the British warship " Charles Ball " sailing the Sunda Strait en route to Hong Kong came within 20 km of the exploding Krakatau volcano and witnessed a great deal of static electricity in the atmosphere, generated by the movement of tiny particles of rocks and droplets of water from the volcano's steam, which caused spectacular brush discharges taking place from the masts and rigging of the ship.
