Electronics Communications Interview Questions And Answers

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

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.

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

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.

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

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

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
the end of the interview you will be clear enough of my
knowledge and my potential. That will help you to decide
whether u sud hire me or not.

While both provide backup power during mains outage, with
the UPS the switch is instantaneous whereas with the
Inverter there is a gap of a second or two. This gap is OK
for household gadgets such as lights, fans, fridge, etc. but
not OK for computers.

In technical terms:

UPS: The mains power comes to the UPS. The AC is converted
to DC and this DC is constantly charging the battery. The
output of the battery is fed to the Sine wave inverter and
it converts DC to AC and this feeds the equipment. Since
power out is always drawn from the battery, there is no time
lag when mains swicthes off; it justs stops the battery from
being charged and the UPS continues to supply power till the
battery runs out.

Inverter: The mains power comes to the Inverter. This is
directly sent to the output but the AC is also converted to
DC and this DC is constantly charging the battery. A sensor
and relay mechanism checks whether the mains is ON or OFF.
When the main switches OFF, the relay actuator triggers to
switch from mains to inverter. Rest is same like the UPS.
Because of this sensor and relay, there is a gap between
triggering.

UPS involves more costly circuitary and is therefor more
expensive to make and sell.

When Transmission power increase the sensitivity of the antenna increase and so the threshold value decrease.

ups is a uninterputed power supply.inverter is invet the
load in DC to AC than load taking the AC.it will be
convertor is convet AC to DC that time battery is
charged.battery connections in series..
