How does a series regulator maintain the output voltage at a constant level?
A series regulator maintains the output voltage at a constant level by constantly changing the effective resistance of the pass device, usually the output transistor.
How does clipping circuits work in lab?
A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
In what part of the circuit do the electric charges releases most of their energy?
The component with the highest resistance in a series circuit will have, or "drop" the most voltage across it. All of the components in a series circuit will have the same amount of current flowing through them but not the same voltage drops if the resistances are different. More resistance more voltage across it, less resistance, less voltage across it.
Relationship between current and brightness of a light bulb?
the current is a factor that affects the brightness of the bulb but there are other factors such as if the circuit is in series or parallel. Overall though the current does affect the brightness of the bulbAnswerFor a lamp to operate at its rated power, it must be subject to its rated voltage. It's as simple as that! This is why a lamp's rated power is listed together with its rated voltage on the glass envelope of any lamp. If the voltage is allowed to fall below its rated voltage, then its power output will fall; in fact, a small fall in voltage will result in a proportionally-larger fall in power.
Do batteries that are arranged in series produce a higher voltage than batteries arranged in parallel?
Batteries in parallel maintain constant voltage across the load rather in a series, so it is better to arrange the batteries in parallel Batteries in series deliver a higher voltage, batteries in parallel have longer life use.
What do you mean by DC generator?
DC generator is used to produce direct current. The basic DC generator have four basic parts 1. A magnetic field 2. A single conductor or loop 3. A commutator 4. Brushes
What will be the output voltage if reference voltage is open circuited in a series voltage regulator?
unregulated voltage minus series regulator transistor drop.
How do you connect Two DC generators together to double the output voltage?
You would connect them in series to double the output voltage.
How does a series regulator maintain the output voltage at a constant level?
A series regulator maintains the output voltage at a constant level by constantly changing the effective resistance of the pass device, usually the output transistor.
Does the voltage output increase when a generator is made to spin faster?
You would have to apply a higher voltage from outside - for example, in the case of DC, connect a battery that provides more voltage, or connect more than one battery in series; or in the case of AC, use a transformer to increase the voltage.
If you have four batteries in series what is the output voltage?
depends on the voltage of the batteries.. four 12 volt car batteries would output 4x12 = 48 v
To increase voltage output when using more then one battery connect the batteries in?
To increase voltage output when using more then one battery connect the batteries in series.
Input resistance and output resistance of Voltage series feedback amplifier?
output resistance decreases and input resistance increases
What is the difference between voltage series and current series feedback amplifier?
I assume a series of amplifiers with one F/B The F/B is the portion of voltage/current F/B from input to output no matter how many amplifiers are in series within the loop or what the gain of each one is.
What are the problems of commutation in a DC generator?
1.resistance commutation 2.e.m.f commutation
What is the total voltage of a battery containing five 2 V cells connected in series?
Total voltage output of 5 2v cells connected in series would be 10v
What Generator has shunt windings and series windings?
A 'compund wound' dc generator has shunt winding and a series winding. The shunt winding has a high resistance, and draws only a small current from the armature, but as it has many turns of wire on it, it generates a strong magnetic field. The series winding has only a few turns of wire on it, and, even though it has a large current in it, its magnetic field is usually less than that of the shunt field. Because of this, the compound generator behaves in most ways like a shunt generator, and is controlled in the same way. As it is self-excited, the compound wound generator requires 'residual flux' to start the generating process. The series winding, if connected to AID the shunt field, can boost the field flux as load comes onto the machine and correct for the normal 'droop' in output voltage as the load increases. If set up properly, this correction makes the generator self-regulating. Because the fields aid each-other, this connection is called 'cumulative compounded'. This type of machine is the workhorse of the larger generator market. If the series field winding is connected so it's field OPPOSES the shunt field, then the output voltage of the generator collapses as the machine is loaded up. This connection is referred to as 'differential compounded', and is only used for arc welding generators - they have a high voltage before the arc is struck; a fairly low voltage during welding operations, and if the rod sticks to the work, they shut the generator down without damaging it.
