What are some properties of mercury?
Mercury has a melting point of -39.9
Does the element Mercury have a melting point?
The melting point of mercury is: 38,83 0C.
What is a three point starter?
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.
The temperature of the mercury in and out?
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.
What is the use of 4 point starter in motors?
in 4 point starter we use a protactive rasistance to control the speed of motar in 3point starter speed is uncontolled
What is the use of 4-point starter in motors?
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.
What is the highest possible hand in cribbage and how is it achieved?
The highest possible hand in cribbage is a 29-point hand, achieved by holding a hand with a Jack of the same suit as the starter card, along with the other three Jacks and the 5 of the same suit as the starter card. This combination results in the maximum possible score of 29 points in a single hand.
Difference between 3 point starter and 4 point starter?
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
