What is the use of dielectric between capacitors?
A dielectric is an insulator between the plates of a capacitor. They allow us to build the plates closer together, without allowing them to short together, thereby increasing capacitance.
What are the limitations of conventional tubes at microwave frequency?
2-3Figure 2-1B.-Interelectrode capacitance in a vacuum tube. 100 MEGAHERTZ.Figure 2-1C.-Interelectrode capacitance in a vacuum tube. INTERELECTRODE CAPACITANCE IN ATUNED-PLATE TUNED-GRID OSCILLATOR.A good point to remember is that the higher the frequency, or the larger the interelectrodecapacitance, the higher will be the current through this capacitance. The circuit in figure 2-1C, shows theinterelectrode capacitance between the grid and the cathode (Cgk) in parallel with the signal source. Asthe frequency of the input signal increases, the effective grid-to-cathode impedance of the tube decreasesbecause of a decrease in the reactance of the interelectrode capacitance. If the signal frequency is 100megahertz or greater, the reactance of the grid-to-cathode capacitance is so small that much of the signalis short-circuited within the tube. Since the interelectrode capacitances are effectively in parallel with thetuned circuits, as shown in figures 2-1A, B, and C, they will also affect the frequency at which the tunedcircuits resonate.Another frequency-limiting factor is the LEAD INDUCTANCE of the tube elements. Since the leadinductances within a tube are effectively in parallel with the interelectrode capacitance, the net effect is toraise the frequency limit. However, the inductance of the cathode lead is common to both the grid andplate circuits. This provides a path for degenerative feedback which reduces overall circuit efficiency.
What are the advantages and disadvantages of transducers?
One of the advantages is thereâ??s minimal loss of analog data and can easily be converted to digital data. The disadvantage is it is sensitive to temperatures and acceleration.
Describe the response of a capacitor when connected to and then disconnected from a battery?
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.
Why is that a space charge region in a pn junction at equilibrium is often made small?
The space charge region in a pn junction at equilibrium is often made small due to:to obtain a high junction capacitance;since the junction capacitance is inversely proportional to the width of the space charge region, the smaller the width, the larger the junction capacitance.to ensure easy diffusion of charge carriers;if the space charge region is made small, that is, the width is made small, the distance for diffusion also becomes short, then it becomes easy for the electrons to diffuse into the p-side and the holes into the n-side
What did Spencer and Freddie sign say after it short circuted?
P e e on Carl
Why wont your computer battery charge?
The battery could have been damaged, wet, or short-circuted.
Why would a 89 Isuzu troopers electrical system just die?
because it needs to be replaced. short circuted
When a three phase generator is short circuted what is the current and voltage?
Hopefully the current and voltage would be zero. The generators overload and short circuit main breaker protection is there just for conditions like that. As soon as the fault is recognized by the protection the generator is taken off line.
How does one reduce stray capacitance?
You can reduce stray capacitance by avoiding having long wires running parallel in circuits. Keep wires as short as possible. Long wires running along each other can exhibit stray capacitance effects. Another way is to cut long leads of components such as capacitors and inductors to make them as short as possible. If best, use SM components, as they have no leads which can cause this stray capacitance effect.
Why capacitance is neglected in short transmission lines?
Wen the length of overhead transmission line is less than 80 km with an operating voltage up to 20kv it is considered as short transmission lines Due to smaller lengths and low operating voltage the charging current is low so the effect of capacitance of short transmission lines is extremely small and therefore can be neglected as in case of distribution lines and only R L is to be taken into account while analyzing short transmission lines
When was Reason - short story - created?
Reason - short story - was created in 1941-04.
Explain the use of a varactor diode in a parallel resonance circuit?
Short answer: By using a varactor diode as the capacitance in a parallel resonant ckt, by changing the reverse bias voltage you change the value of capacitance which in turn changes the resonant frequency. This makes a tuneable resonant ckt.
What is a good reason to read a short story?
You read stories to be entertained, or to learn information. A short attention span is a good reason to read a short story.
Why are transmission lines less than 80km considered short?
The transmission lines which have length less than 80 km are generally referred as short transmission lines. For short length, the shunt capacitance of this type of line is neglected and other parameters like electrical resistance and inductor of these short lines are lumped.
What is the function of capacitance?
The main purpose of a capacitor is to electrostatically store energy in an electric field. It is originally known as condenser.
Why h parameter are not used for transistor mode at high frequency?
finding h parameters involves open and short circuits which is difficult to obtain at high frequencies due to stray inductance and capacitance
