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.

In a parallel circuit what is the total current equal to?
In all branches of a parallel circuit, it is voltage that is the same. Across each parallel branch of a circuit, we'll measure the same voltage. Probably the best example of equal voltages appearing across all branches of a parallel circuit is a household electrical distribution curcuit. The voltage at any outlet where you'd care to plug in an appliance or device will be the same. A fan plugged into an outlet in a bedroom will "feel" the same voltage as it would if it were in the living room and plugged into an outlet there.
One other way to look at things like this is that each branch of the parallel circuit is connected across the voltage source. Each branch could be looked at as an "independent" circuit, and any given branch doesn't care what is happening in any other branch. Does turning that fan we mentioned on and off, or even unplugging it from the outlet affect the operation of, say, the refrigerator? No, it does not. Any device plugged into an outlet is connected "directly" to the source of voltage. And each parallel branch of the circuit will operate independently of any other branch. We know that the voltage in (or across) any branch of a parallel circuit is the same as the voltage across any other branch.
The first statement is true, the motor needs a power source to operate.

When did the last circuit city store close?
Circuit city closed it's doors in early 2009. However, systemax Inc purchased circuit city in may, and reopened the circuitcity.com website. Check it out! Systemax also owns Tigerdirect USA, Tigerdirect Canada, Comp USA, Micro Europe, Global Computer, Info Tel USA, and Systemax PC.
What is cb configuration of the transistor?
A sexy transistor are two type. NPN and PNP..... c means common b means base .
WHAT IS the differences between analog and digital sensors?
Digital sensors produce digital output (0 or 1) which can be easy to communicate directly with a microcontroller. Analog sensors provide analog outputs which one must firstly digitize to sense the level. Analog sensors are generally more accurate.
What is the maximum reading in ohms for grounding purposes?
Generally lower earth resistance is preferable but for certain applications following earth resistance are satisfactory
Large Power Station s– 0.5 Ohm
Major Power Stations - 1.0 Ohm
Small Substation – 2.0 Ohm
In all Other Cases – 8.0 Ohm
What is a transformer and what principle is used in transformer?
A transformer is a static device which converts electrical energy from one circuit to another circuit without changing frequency, power, power factor.
It works on the principle of faradays laws of electro magnetic induction.
Who was the firs person to produce an electric current bby moving a wire through a magnetic field?
Michael Faraday
What is characteristics of current source?
The characteristic of the current sources is that it cannot operate in an pen circuit.
What are the fundamental logical gates?
The inverter, which returns the reverse of the input. The AND gate which returns a high output if and only if both inputs are high. The OR gate, which returns a high output if either or both inputs are high. The NAND and NOR gates return the opposite of their counterparts. They are basically the AND and OR gates with an inverter after them. The XOR gate is the exclusive OR gate; it returns a high output it either input is high, but not both. Every binary combination of outputs can be made from these operators. In fact, you don't even need all of them. The NAND and the NOR gate can both create every other gate.
What would be a typical magnitude for the reverse current in a general-purpose silicon diode?
It depends on the particular diode. They range from around a hundred volts to several thousand volts, depending on what you want to spend.
How do you perform Parallel Adder Addition?
A binary parallel adder is a digital function that produces arithmetic sum of two binary numbers in parallel.
It consists of full-adder combinational arrangement thus, the output carry from one full adder connected to the input carry of next full- adder.
Why use inductors in transistor amplifier circuit?
Audio power amplifiers usually separate the last inductor in the output stage transmission chain. The last inductor usually receives the most attention when it comes to power efficiency in a circuit.
Since circuits experience opposition to current, especially where current is changing direction, capacitive reactance or opposition needs to be balanced with inductive reactance. This is done with the help of an output inductor for maximum output to be reached.
Output inductors are used to dampen circuit resonance with the help of a shunt resistor. This is especially important in high frequency circuits where stability is a real issue.
How do you make a digital object counter?
A: First you need a object detector that give out a pulse per each. That becomes the clock for any the input to a counter that will count up in binary coded decimal and of these there are many to choose from. Eventually it will fill up and starts over unless there is a reset along the time of counting. that is the basic.
How do you make a Navigation system?
it's just like an GPS System but it's a different type and made from a different com[any.........lolzz
What is pulse position modulation and demodulation?
It is used for the radio control of model aircraft,boats, cars.
Why should the secondary of a power transformer not to be left on an open circuit?
In general there is no reason why it should not be, though there may be special situations. Perhaps there is confusion with CURRENT transformers which must not be left open circuit because of the high voltages which they will produce. it may trip the CB. although there is no faults but a high current called Inrush current is flow when the the power transfomer energized while its secondry circuit is open
Difference between analog modulation and digital modulation?
Analog Pulse modulation is discreet in time but the formation is transmitted in continuous form. In digital pulse modulation, not only the time axis is discreet but the information is also in digital form.
Examples of Analog PM are PAM and PTM i.e pulse amplitude and pulse time modulations respectively.
Examples of Digital PM are PCM and PDM i.e pulse code and pulse delta modulations respectively.
