it conducts in only one direction. it can also be used as a switch and made to not conduct at all.

Yes, it can. Then you can use the charge to power something else. :)

is a system of equipment used for microwave data transmission.

A half wave rectifier conducts on every other cycle. The output is a train of half sine cycles, at a period equal to the input period. At 60 Hz, the period is 16.7 ms. Each half cycle (8.3 ms) will be interleaved with periods (8.3 ms) of no voltage. If you filter the output with a capacitor, you get DC - at no load, the DC will be the peak value less the forward bias voltage of the diode - at some load, the DC will fluctuate between that peak value and some value dependent on the size of the capacitor and the current draw. Again, the period (of this nearly sawtooth waveform) will be the input period.

A full wave rectifier conducts on every cycle. The output is a train of half sine cycles, at a period equal to half the input period. At 60 Hz, the period is 8.3 ms. Each cycle (8.3 ms) will be connected to the preceding cycle with no intervening delay. Each cycle will pulse in the same direction, instead of in alternating directions. If you filter the output with a capacitor, you get DC - at no load, the DC will be the peak value less the forward bias voltage of the diode - at some load, the DC will fluctuate between that peak value and some value dependent on the size of the capacitor and the current draw. Again, the period (of the nearly sawtooth waveform) will be half the input period.

Since the full wave output waveform is twice the frequency (half the period) of the half wave output, the capacitor can be about half its required value for the half wave circuit in order to achieve the same level of filtering.

A: Noise effect an analog signal by adding or subtracting from the signal

the current value at any part of the circuit is dependent upon the circuit conditions and not the ammeter. The meter will simply allow you to read those currents, whatever they may be.

who knows 30kva means 30000 volts per ampere so if the output is 100 volts the amps will be 300 amps so do the math.

89c51 microcontroller is of the series of 8051,one of oldest yet commonly used microcontroller.89c51 have the less complex features then other microcontroller and it is also easily available and cheap in comparison of other microcontrollers.

Diodes are used for a number of different purposes. Its most common function, however, is to act as a semi-conductor in a variety of commonly used household appliances.

Those are electrons.

Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines

No, not unless there is a 115-volt power inverter to convert the 12 VDC to AC at the higher voltage. There are inexpensive inverters available to plug into a cigarette lighter outlet in a 12V vehicle system, but only for up to about 150 watts.

t = L/R

the source current is the current that flows from the power source.

voltage

Most people say electrons (which are negatively charged). Some who are really out there might say it's a flow of holes moving the other direction.

BJT is a current controlled device because its output current is dependent upon the current in the base while for FET it is controlled by the voltage at the gate terminal of the transistor.

BJT is a current controlled device because its base current is not zero while for a FET the gate current is zero

Crystal diode for a p-type semiconductor and n-type semiconductor formation of the pn junction, in its interface on both sides of a space-charge layer, and has a self-built electric field. When there is no applied voltage, as pn junction on both sides of carrier concentration caused by the proliferation of poor self-built electric current and drift arising from the current equivalent and the balance of power in the state.

When the outside world a positive bias voltage, electric and outside the field of mutual self-suppression role of the Consumers carrier increase from the current spread of the forward current.

When the outside world a reverse bias voltage, external electric field and to further strengthen self-built electric field, in a certain form of reverse voltage and reverse bias voltage value unrelated to reverse saturated current I0.

When the reverse voltage applied to a certain high level, pn junction in the space charge of the electric field strength to achieve the critical values of the double-carrier process, a large amount of electronic hole right, had a great numerical breakdown of the reverse current, Breakdown phenomenon known as diodes.

This question is from Bohr's atomic model. The total length of the orbit is an integral multiple of the wavelength of an electron. The relation given by 2(pi)(radius)=n(wavelength), where n is the principal quantum number. Proof of this came later from De-Broglie's hypothesis,

(wavelength)=h/(linear momentum)

It is-

(wavelength)=h/mv .....I

From Bohr's model (Quantization of angular momentum),

mvr=nh/2(pi)

So,

2(pi)r=n(h/mv)

From I,

2(pi)r=n(wavelength)

A diode is basically a electronic non return valve it let current flow in one direction only and can not be used for amplification it only consist of a cathode and anode, where the transistor can be used in many applications, for instance as an amplifier, electronic switch, oscillator etc. it consist of three connections eg. Collector, Emitter and a Base normally the current is collected at the Collector and emitted at the Emitter and the Base is used to control the current flow with the Base at 0 volt no or very little current will flow between C and E it will only switch on with the B at about 2.7volt and the higher the B voltage the more current will flow thru the transistor

The purpose of the battery in a circuit is to wive energy to the circuit
