Q: How tube light circuit is connected and how it works?
A:A
choke is connected in one end of the tube light and a starter is in
series with the circuit. When supply is provided ,the starter will
interrupt the supply cycle of AC. Due to the sudden change of supply the
chock will generate around 1000volts . This volt will capable of to
break the electrons inside the tube to make electron flow. once the
current passes through the tube the starter circuit will be out of part.
now there is no change of supply causes choke voltage normalized and
act as minimize the current.
Q: whats is MARX CIRCUIT?
A:It
is used with generators for charging a number of capacitor in parallel
and discharging them in series.It is used when voltage required for
testing is higher than the available.
Q: What is encoder, how it function?
A:An
encoder is a device used to change a signal (such as a bitstream) or
data into a code. The code may serve any of a number of purposes such as
compressing information for transmission or storage, encrypting or
adding redundancies to the input code, or translating from one code to
another. This is usually done by means of a programmed
algorithm,especially if any part is digital, while most analog encoding
is done with analog circuitry.
Q: What are the advantages of speed control using thyristor?
A:Advantages :1. Fast Switching Characterstics than Mosfet, BJT, IGBT 2. Low cost 3. Higher Accurate.
Q: Why Human body feel Electric shock ?? n in an Electric train during running , We did nt feel any Shock ? why?
A:Unfortunately
our body is a pretty good conductor of electricity, The golden rule is
Current takes the lowest resistant path if you have insulation to our
feet as the circuit is not complete (wearing rubber footwear which doing
some repairs is advisable as our footwear is a high resistance path not
much current flows through our body).The electric train is well
insulated from its electrical system.
Q: what is the principle of motor?
A:Whenever
a current carrying conductor is placed in an magnetic field it produce
turning or twisting movemnt is called as torque.
