16 Electronics Communications Questions and Answers:

1 :: What is the basic difference between latches and flip flops?

flip flops have clock signal whiles latches dont need any
clock pulse..

2 :: What is race aroun condition in flip flop?

in a jk flip flop(level triggerd) when J=1,k=1......the
output Q continuosly keep changing between 1 and 0 as long
as clock is high.....this is called race around condition.

3 :: If a crow sit on on current wire it will not fell current but a man touch it he get shock . why?

1) there is no grond termainal (-ve terminal to complete path),
2) tere is no conductor (conduction medium) In tere leg.

4 :: Why 2 rectifier is used in smps?

Its not necessary that a power plant uses only two
rectifiers, it depends on the load present at the site and
the capacity of the rectifier or SMPS. Suppose the load at
the site is 120 Amps and the SMPS capacity is 2000W or the
current capacity of the recifier is 50 Amps. In that case 3
or more rectifiers is preffered. Rectifiers is used to
balance the load in each phase.

5 :: What is difference between voltage and potential?

Voltage is referred as Potenial difference between two points.potential means its force. I think so.voltage defination is 100% correct.

6 :: Why always current in some amp and voltage is 230?

current is depending upon the load. ByOhm's law,
V -lR,here load is variable.v-230v so current is depending upon your load

7 :: Why I hire you and why i dont hire you?

You should hire me because I meet the eligibility criteria
asked by you. Even I had the experience in this relevant
field. I am a good team player. For the second question at
