if the starter is good , then its possible. do you know how to do it?
Mercury has a melting point of -39.9
The melting point of mercury is: 38,83 0C.
A three point starter is a device that is meant to help start a DC motor. A three point starter will start device without much starting current.
Ans- majit khan -we know starter is a safety device. Two point starter is used for Dc series motor. In two point starter all the thing's are connected in series.
The freezing point of mercury is -38,8290 0C.The boiling point of mercury is 356,73 0C.The temperature of mercury indoor or outdoor is the temperature of the environment.
in 4 point starter we use a protactive rasistance to control the speed of motar in 3point starter speed is uncontolled
The boiling point of mercury is about 357oC
The four-point starter eliminates the drawback of the three-point starter. In addition to the same three points that were in use with the three-point starter, the other side of the line, L1, is the fourth point brought to the starter when the arm is moved from the "Off" position. The coil of the holding magnet is connected across the line. The holding magnet and starting resistors function identical as in the three-point starter. * The possibility of accidentally opening the field circuit is quite remote. The four-point starter provides the no-voltage protection to the motor. If the power fails, the motor is disconnected from the line.
The melting point of mercury is -38,83 0C. The boiling point of mercury is 356,73 0C.
1." the shunt connection in four point stater is provided separately form the line where as in three point stater it is connected with line which is the drawback in three point starter 2.In three point starter NVR (no voltage relay)is series with shunt if voltage falls certain value NVR De energized due to insufficient magnetic field and motor turned off. But in four point starter NVR energized directly from DC supply thus the draw back of 3 point starter rectified
The freezing point of mercury is -38,829 0C.
The boiling point for the element Mercury is 674.1 degrees Fahrenheit. Mercury can also freeze and melt at different temperatures.
