Question1: Is it possible to
start up a 36w or 40w 220V AC/DC tube light without the help of Coil or Choke?
start up a 36w or 40w 220V AC/DC tube light without the help of Coil or Choke?
Answer 1: It is not possible
without the help of electric coil or choke. Because, the coil or choke ionize
the particles in the tube light. In normal voltage it is not possible to ionize
the particle.

Question2: What is the
difference between three point and four point starters?
difference between three point and four point starters?
Answer 2: In the four point starter the line and Shunt
are connected separately. In the three point starter the line and shunt are
connected in same. This is one of the advantages of three point starter.

Question 3: What types of
resistance is used in bulbs or tube lights? What will happen if a 220volt AC
operated bulb or device run by the 220volt DC?
resistance is used in bulbs or tube lights? What will happen if a 220volt AC
operated bulb or device run by the 220volt DC?
Answer 3: The AC operated Bulb or device has a very low
resistance. But, the devices whose are designed for AC offers high impedance to
the supply. When the DC voltage is applied to the AC devices, the passing DC
current is very high due to the low resistance of the device. This high voltage
may damage the device.

Question 4: What do you mean
by electric traction?
by electric traction?
Answer 4: Electric Traction means running a machine by using electric energy or
power. Electrical energy, energies the traction system. Basically DC motors are
used in traction system. Now electric traction system widely used in trams,
trolleys, industries, railways .Bullet train is also running by the magnetic
traction, magnetism is setup by the electric energy in the bullet train.

Question 5: Why the capacitor
works doesn’t work on DC?
works doesn’t work on DC?
Answer 5: The capacitor
normally gives an infinite resistance to DC component. But, it allows AC power
component to pass through the devices. These resistances of the capacitor
blocks work of DC component.
