rectifier, it is a n electrical device that converts ths high votage carrying AC to low voltage carrying DC

Yes. You need two gated input SR flipflops, and an inverter.

Connect the Q output of the first flipflop to the S of the second.

Connect the notQ output of the first flipflop to the R of the second.

Connect the clock to the gate input of the second flipflop, and to the input of the inverter.

Connect the output of the inverter to the gate of the first flipflop.

The potential across a pn junction is called potential barrier because majority charge carriers have to overcome this potential before crossing the junction.

rotating anode

1)During a operation large shaped disc tungsten anode rotate at speed 3000 t0 9000rpm(resolution per minute).

2)A motive force to rotate the anode is given by induction motor.therefore windings of which is housed outside the tube.

3)a design element help to limit power density delivered on the physical focal spot while making a small effective focal spot.

4)with rotating anode,heat is produced during exposure is spread over the large area of anode.thereby increases the heating loading capacity of the tube and allowing high power level are used as a result which produces the x radiation.

5) by increasing the anode voltage x rays which produces the shortest wavelength this is used to therpeutic.

by decresing the anode current which produces the longest wavelength this is used for diagnostic process.

In case of parallel circuit the effective resistance is given by

Reff = R1*R2*R3 /(R1R2 +R2R3 +R3R1)

As short circuit takes place then anyone R1,R2,R3 becomes zero. Hence Reff becomes zero.

A block diagram of monochrome TV transmitter can be written out on paper. The diagram is broke don on drawn blocks and in the blocks is data that is used to explain monochrome TV transmitter.

Answer Pmax=E^2/(4xRs)

The maximum power is transferred when the load impedance is the complex conjugate of the source impedance. For a dc circuit or a purely resistive circuit, the load resistance equals the source resistance.

let me answer you in layman terms. you can say 1000VA means 1000watt (like in DC circuit).

All electrical devices are made of various components. Two very important components which you would find in almost all the electrical devices are capacitor and inductor.

Now due to these components you will not receive all the power i.e.1000watt.

It might be 980watt. Now the actually power was 1000, which is called apparent power,

but power transmitted was 980, which is called, real power because that is what reached at the end terminal.

But in real terms volt-ampere or VA is unit of apparent power in an AC circuit containing capacitive or inductive reactance(reactance is opposition caused by electronic components to ac current due to capacitance or inductance). Apparent power is the product of source voltage and current i.e. 1VA is the power dessipated when one volt produce one ampere current.

A parallel resonant circuit has at its heart an inductorand a capacitor. These are the two parallel components. They each react to voltage and current 180 degrees out of phase with each other. When we "hit" this circuit, called a parallel tank circuit, or just a tank, with voltage, one component is "putting energy into the circuit" while the other one is "storing it up" and then the two components switch roles. The result is that the tank will oscillate, and the frequency of oscillation will be determined by the value of the capacitor and the inductor.

wire will move - there is a force acting on it.

it's direction depends upon the orientation of current and magnetic field - a nice way to see this is by looking op a Google picture of Fleming's left hand rule.

the force depends upon the strength of magnetic field, current and length of conductor (perpendicular to field) in the magnetic field.

One jk flip-flop with j=k=1 should be added to the system so that it's modulus becomes 16 instead of 8.

Use a multimeter that has both scales on it . All you need to do is change the scale from AC to DC

Since the breaker that is installed on the generator set will be sized to the output of the 30 kW generator, the load will stay connected until the thermal trip of the breaker trips the load off line. This will be in the matter of seconds before it happens. To handle a 75 kW load and depending if it is an inductive or a resistive load you will need at least a 80 to 100 kW generator.

some are:

1.) zero output impedance.

2.) perfect voltage regulation, especially no voltage over/undershoot with stepped loads.

3.) over-current protection by hard limiting or fold-back.

Others may have different opinions or preferences.

Answer: Yes provided, that its big enough and have good exposure to sunlight, then it can supply charging power to a set of batteries that is connected to an invertor to invert the batteries DC power, to mains AC, preferably a sine wave to drive induction motors and transformers, a square wave tend to make induction motors noisy and transformers don't work to there full capacity .

Transformers have windings - typically each winding is designated for a particular voltage. Any one of the windings can be an "output", as any winding can be an "input". Usually for consumers, one of the windings is intended to be 120V for the input. In that case, all of the other windings would be an output.

I should also mention that while you can have several outputs, you can only have one input. Some transformers have the windings color coded to designate input and outputs.

Hope this helps!

When the pn junction is forward biased,the height of the potential barrier is reduced allowing more majority charge carriers ti flow across the junction and when it is reversed biased, the height of the potential barrier increases there b reducing the majority charge carrier that have sufficient energy to flow across the junction.

Well, a pure sine wave can only be produced as a pure sine wave. If it was modified to begin with, it would never be a pure sine wave. However, an actual generator should be supplying pure sine wave output, while something such as an inverter would be producing a modified sine wave.
