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.

What is center tap transformer?

Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.

What is effective voltage?

It is the 'as if' voltage in an AC circuit. Referred to as Vrms 120 volts in your house is Vrms, the effective voltage, 'as if' it were DC 120V, can do the same work. But 120VACrms is a sine wave with a peak voltage much higher than 120 volts.

List of active transducer?

thermocouple,piezoelectric transducer,photoelectric transducer.

What is relation between size of conductor and voltage?

It depends on the type of Power systems Whether AC ( single or multi phases) or DC ( 2 or 3 wire ) .....ETc

How much does a 4017 IC cost?

Depending on the package type and where you buy it, one 4017 costs somewhere between $0.30 and $1.00 US.

How monostable multivibrator can be used to generate?

we can use monostable multivibrator.But generally its o/p is a square wave so to get a pulse type waveform,we may use differentiator after monostable multivibrator....

What is the difference between a PIC chip and a 555 chip?

PIC's are programmable microcontroller chips made by Microchip Inc. PIC's can be programmed to do timing functions, but they can do many other things as well.

555's are dedicated purpose timer chips made by several different manufacturers. They have no intelligence, they are strictly analog electronics.

How do you stop lan school?

Download lanschooled or simply pull the internet cable out of the back of the computer.

Download lanschooled or simply pull the internet cable out of the back of the computer.

If you pull out the network cable, you will no longer be conected to your schools network, meanig you wont be logged onto anything and wont have internet aCESS

What are the criteria for choosing a microcontroller?

1. Meeting the computer needs of the task efficiently & cost effectively-

· Speed , the amount of the ROM & RAM, the no. of the i/o ports & timers, size, packaging, power consumption.

· Easy to upgrade.

2. Availability of software develop tool-

· Assembler. Debugger(use in check syntax), Compiler, emulator(hard wire).

Wide availability & reliable source of microcontroller

How do you convert ohms to mega ohms?

A Megohm is one million ohms. To convert ohms to Megohms, divide by one million.

Where is a variable resistor in your home?

If you have a light switch where you can brightener it or dim it that is a VARIABLE RESISTOR.

Explain how a current flows in a semiconducting diode in the two states of biasing?

Let me answer as I've learned.

In this case, if the voltage source for forward bias is greater than the voltage source for reverse bias, current will flow in this semiconductive diode.

And another way may occur. That is, in case reverse bias voltage is as large as breakdown voltage, reverse breakdown current ,which is because of the minority carrier in p region, will flow and this current can be large to damage the diode.

If there is any mistake in my answer, please correct me and I'll thank you for that.

What does it mean if a voltmeter has low sensitivity?

Going back in time, meters were rated in ohms per volt full scale sensitivity. This means that if a meter was rated at 20Kohms per volt and it had a 1 volt scale, it would represent a 20Kohm additional load on the circuit it was attached to. In some circuits the additional load could change the operation of the circuit, and/or the measurement. Analog meters usually had this rating. I guess very cheap ones today are still this way.

Modern meters generally have a sensitivity in excess of 11Megaohms/volt, so this is no longer a problem for simple measurements.

Can we use AC capacitor in surge suppression circuit DC?

A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.

What are the function of transmitter?

function of transmitter:-

1. generate a signal of desired correct transmitting frequency

2. modulation

3. power amplification

What is an arthrogryposis multiplex?

Non progressive disorder with multiple congenitally rigid joints. Associated with a decrease in anterior horn cells and other neural elements of the spinal cord. Normal intelligence. Miller Review of Orthopaedics
