Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.
24,372 Questions
What is a transducer in an analytical instrument?
Photoelectric or, more commonly, an ionization chamber
How do you identify capacitor's anode and cathod?
In ceramic capacitors if you observe it then one of its terminal is smaller than other one.Thus,the longest one is its anode and other one is its cathode.
The SIGNAL statement is used to clear the diagnostics area
Why ripple carry adder is used?
A ripple carry adder needs a much less complicated circuit, than other adder topologies.
What is the purpose of a radar synchronizer?
purpose of a radar synchronizer is to control timing throughout the system.
How do you use scr as a diode?
scr is basically a three terminal device can be used as diode by leaving one terminal
Is electric cooker connected in series or parallel?
All residential loads are connected in parallel, so that they share the same supply voltage, which is necessary for them to develop their rated power outputs.
What is the importance of the wattage of a resistor?
it can't handle more power than that rated wattage. exceed the rating and it burns out.
Why different frequencies has same average value and RMS value?
Voltage and frequency are independent quantities.
AnswerBecause the r.m.s. value is dependent on the shape of the waveform, not its frequency. The average value of any symmetrical waveform is zero and is independent of frequency.
How is a galvanometer sensitive?
GALVANOMETER detects very small currents in terms of milli amperes so it is said to be called as sensitive
What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?
They both have the same current.
5 megohms
Why it is desirable for an op amp to have a high CMRR?
A high CMRR prevents the opamp from passing undesirable common mode signals.
Calculate the voltage of a battery if the resistance is 80 ohms and the current is 0.5 amp?
Ohm's law: Voltage is resistance times current.
80 ohms time 0.5 amperes = 40 volts.
Why are charge capacitors dangerous?
Charge Capacitors , like all capacitors shift the voltage 90 degrees, tiny one form tuned circuits and do a multiple of functions like blocking DC and allowing AC to pass . But as your name indicates a charge or charged Capacitor can kill you with shock . Or simply knock you silly for a fraction of second .
How much electricity does it take to light up a street lamp?
Depends on the type of lamp.
- Mercury vapor
- High Pressure Sodium
- Low Pressure Sodium
- etc.
Why voltage gain of a common collecter amplifier is 1?
actually it is slightly less than 1, due to base-emitter forward bias voltage.
In order to work CD4033 IC, you will need to put the correct pins in the circuit board. If you do not know what you are doing with the board, you should seek a professional for assistance.
What is the conductance of a circuit that has ten ohm resistance?
0.1 mhos
mhos = 1 / ohms
Another Answer'Conductance' is the reciprocal of resistance, and its SI unit of measurement is the siemens (symbol: S). The 'mho', its former unit, has not been used since the 1960s. So the answer is 0.1 S.How does motion of electron in n type substance differes from motion of hole in p type substance?
Electrons constitute electronic current in n-type substance and holes constitute conventional current in p-type substance.The motion of electron in a n-type substance is opposite to that of holes in a p-type substance.
What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
What is the wavelength of DC current?
Unlike AC, which HAS waves, DC current is waveless- either on or off. No waves= no wave length.
