A device that initiates a flow of high voltage across the electrodes of a fluorescent lamp.AnswerFluorescent Lamp StarterA fluorescent tube has a heater at opposite ends of the tube. These are connected in series with the supply via a 'starter' (a small, heat-operated switch). When the tube is first switched on, current flows through the heaters which then act to ionise the gas within the tube. Once the gas is ionised, it begins to conduct and illuminate the tube. At this point the current flow through the heaters can be discontinued. This is done by the 'starter', a heat-operated switch, which opens a few moments after the current begins to flow. This arrangement is called a 'starter circuit' for a fluorescent tube.Motor StarterBut there is also a 'starter' for an electric motor. Many motors cannot be started merely by connecting them to the supply. This is because, on starting, many motors demand a very large 'starting current' which reduces as the motor begins to turn. A motor 'starter' is used to restrict the amount of starting current until the motor runs up to speed.

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.
Yes! · To accelerate the motor to the rated speed · To limit the starting current in the armature to a safe value · To disconnect the motor in case of a supply failure or overload
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.
in 4 point starter we use a protactive rasistance to control the speed of motar in 3point starter speed is uncontolled
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

If the graph of the function is a continuous line then the function is differentiable. Also if the graph suddenly make a deviation at any point then the function is not differentiable at that point . The slope of a tangent at any point of the graph gives the derivative of the function at that point.
The depth of a lake at a center point is a function of the distance of that point from shore.
a spot on the armature that is worn to the point of starter not functioning. a replacement re manufactured starter is in order.
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
Because it has three terminals L , F and A L - Line (connected to Supply) F - Field (connected to field of dc motor) A - Armature (connected to armature of DC motor) that's y it is called 3 point starter :)
When starter handle moved to first stud a reduced voltage is applied
