Electronics Engineering

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.

The PIC is a specific architecture of microcontroller.

The characteristic of the current sources is that it cannot operate in an pen circuit.

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.

It depends on the particular diode. They range from around a hundred volts to several thousand volts, depending on what you want to spend.

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.

the unit of "e.m.f" is "volt"

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.

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.

it's just like an GPS System but it's a different type and made from a different com[any.........lolzz

It is used for the radio control of model aircraft,boats, cars.

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

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.

cheaper than closed loop

open loop

turn the switch you assume the light is on

closed loop

turn the switch observe the current observe the light level...

can predict how much below optimal the performance is and predict when total failure will occur

An RC Transmitter will transmit the signal from your remote to the RC vehicle, allowing you to control it's movements, drive it around within the signal radius and perform tricks.

The kind of material used in a device depends on its requirements and functions. Semiconductors are used where we need moderate conductivity, conductors are used where we need very high conductivity.

Junction diodes(a semiconductor device) allows electricity to pass in one direction and can be used as rectifier. Conductors can't do this. Transistors and LED are other applications of semiconductor.

Note that generally devices are made of both conductors and semiconductors.

It resist the flow of current according to the resistance value.

Most control signals in electronics are active-low signals (usually reset lines, chip select lines and so on). This stems from the fact that most logic families can sink more current than they can source, so fanout and noise immunity increase. (The reason for this is ultimately related to the fact that electrons are negatively charged.) It also allows for wired-OR logic if the logic gates are open-collector/open-drain with a pull-up resistor. Examples of this are the I²C bus and Controller Area Network (CAN).
