The capacitor in which only a specific number of electric lines or electrons can pass through a unit area is called as 'Flux Capacitor'

There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.

As frequency increase the wave length decreases like a beam of light it cannot bend therefore directional

Line regulation defines as the output voltage of the zener to remain constant under input line variation. Load regulations defined as the load increases or decreases the zener will control this variation by keeping the voltage constant.

A current source ideally should be with an internal impedance of 0 zero. So even if the output is zero volts current can flow.

Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.

Secondary breakdown is a drawback of bipolar junction transistors (BJT's), particularly in power transistors. Simply put, when high current flow causes a build up of electric fields inside of the semiconductor crystal creating "hot spots" which cause the transistor to fail.

At the large collector current, the collector to emitter drops. due to drop in voltage,collector current increases in power dessipation. this power dessipation is liocalized in highly concentrated region. In this region temperature increases rapidly.

Semiconductor material, regardless if it is P-type or N-type has a negative temperature coefficient meaning that when temperature increases its resistance decreases. Ohm's Law states that Voltage equals Current times Resistance which shows that as resistance decreases current increases. Since Power equals Current times Voltage, if current increases then power increases. A bi-product of power is heat. So, in these hot spots increased current creates heat in a small area which causes resistance to decrease in that area causing higher current flow in that area causing a further increase of heat. The domino effect eventually causes the transistor to fail.

Short the inputs together.

Logic: A High input, with the inputs shorted together, will be H+H at the input side of the NAND gate, therefore resulting in a low output.

A Low input, with both inputs shorted together, is L+L for inputs, resulting in a High output.

Also, a NOR gate can be used in exactly the same way.

No. The larger the conductor the lower the resistance and the higher the ampacity.

The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.

The reduction in the size of the circuit in a microprocessor will (generally) allow the device to be run at higher clock speeds. This will be due to shorter circuit pathways. It will also increase the challenges related to keeping the device cool, and there are some other variables that come into play when we scale something like a micro-p down.

Triangle-wave voltage signal is a periodic signal that always has a constant positive and negative slope and no zero slope. It is exactly how it is sounds... a triangle shaped wave.

/\/\/\/\/\/\/\/\/\/ - just like that.

Nothing in this world can naturally produce perfect triangle waves. Every vibrates as periodic sinusoid. Triangle waves can be generated from sin waves with the use of Fourier Series.

http://en.wikipedia.org/wiki/Fourier_series

By summing sin waves with different periods nearly any time-continuous signal can be created.

The delay is calculated in 8085 by making the use of formulas. Because of the complexity of the mathematical operations a calculator may also be required.

Channel noise in communication systems is the crackling or high-pitched noises you get in addition to what you want to hear. It is often caused by external electronic interference.

1. stability factor s for voltage divider or self bias is less as compared to other biasing circuits . So this circuit is more stable and hence it is most commonly used.

2. this circuit is used where only moderate changes in ambient temperature are expected

3. the bias automatically adjusts to any variations in the circuit.

LC means coil capacitance circuit RC means resistance capacitance circuit

The working principle of these instruments is same as that of the d'Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and a scale.

The basic principle of this device is the interaction of magnetic field of the compass (a permanent magnet) and the field around the conductor (a simple electromagnet)

In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
