Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
What is Coefficient of coupling?
It is a measure of how close is a coupling between two coils it gives an idea of wat portion of the flux produced by one coil links with the other coil
How do you balance a Wheatstone bridge with one capacitor in the circuit?
Find the value of capacitor that gives you a zero output current. You can try doing ac analysis on some software or do some hand calculations to get an approximate.
How do you measure the capacitance of 3 phase capacitor in active line voltage of 3 phase circuit?
You measure the capacitance of a capacitor in an active circuit by observing the voltage across it and the current through it. That gives you, by Ohm's law, the impedance of the capacitor. Plug that in the the equation for capacitive reactance, and you get capacitance. Note: There is no such thing as a three phase capacitor. A capacitor is a two terminal device that resists a change in voltage inversely proportional to its capacitance. You connect one capacitor to one phase. If you have a "three phase capacitor", then you are talking about three capacitors. Deal with each one separately.
Car Audio Amplified?
A car audio system is nothing without its amplification device. It’s the heart and soul of the car audio world. It’s what makes everything go, so adding a good car amplifier to your sound system is a crucial component of the car audio purchasing process. The reason the amplifier is so crucial is because the amplifier is what gives the speakers their power. The bigger the amplifier, the louder the speakers can be. The amplifier takes the sound signal that’s being generated by the head unit and boosts it before sending that signal to the speakers. It’s essential that you find the right amplifier for your car stereo system. Yes, you can overdo it, so make sure you realize what you’re working with. It’s likely that you’ll want to upgrade your speakers before adding an amplifier, because you can completely blow them out if you’re not careful. Amplifiers are measured by how many watts they produce, and the wattage can range anywhere from 40 to 1,500 watts or more. Obviously, the higher-watt amplifiers are going to come with a higher price tag as well as the added signal boost that you’ll get from the increased power. Make sure you budget properly, because the top-of-the-line amps can run you $500 or more. Another thing you’ll want to consider when looking for an amplifier is the size. Amplifiers come in many different shapes and sizes. You’ll want to measure the space you have in your trunk or wherever you plan to place the amplifier before you purchase it. You don’t want to purchase an amplifier that is too big for the allotted space. All factors considered, adding an amplifier is going to give your car audio system a huge boost. Depending on the amplifier you add, people should definitely be able to hear you coming, no matter what kind of car you drive.
Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
transformer coupling
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Which coupling gives the higher gain in case of amplifier?
DC coupling on the input/output will always give higher gain because AC coupling involves inserting a capacitor, which adds impedance and augments the signal. AC coupling is sometimes necessary though, for such purposes as eliminating DC offset on the base of a transistor, or eliminating a DC offset in a single supply opamp circuit.
How many type of coupling?
For most parts of electronics is concerned,there are two types of coupling in any alternating current source (AC) circuits: 1)capacitive coupling(Also known as the AC coupling) 2)Inductive Coupling(Also known as the Transformer coupling) Two circuits of different amplification factors and different hybrid parameter values can be merged or coupled by means of a capacitor (capacitive coupling) or an inductor or a transformer (inductive coupling).There are coupling coefficients involved with the transformer.But Capacitor blocks DC and allows AC most of the time.We use ceramic capacitors for this purpose.However never replace the ceramic capacitor with an electrolytic capacitor .Electrolytic capacitors are strictly polar while ceramic capacitors are not.Electrolytic capacitors are used as bypass capacitors.They bypass the current from the resistances that are parallel to them during high frequencies.This is so because the reactance of the capacitor is low at such high frequencies.Also current takes the least resistance path.As reactance gives the AC equivalent of the resistance,current flows into the capacitor while resistance and capacitors are connected end-end and thus the current reaches the other node(its like a diversion or a detour or a shortcut on the road for vehicles-analogously it is the simplest path a current can follow on the conductor
What is the simplest way to convert capacitance to voltage?
If it is a variable cap, apply AC signal to the capacitor as per its specifications.This is done because the variation in the voltage gives a corresponding current output due to the charging and discharging of capacitor. Then a Trans-impedance amplifier can be used to convert this input current to voltage. Current amplifier can be used to amplify the current at the input of the trans-impedance amplifier. Similarly a voltage amplifier can be used at the out put of the trans-impedance amplifier to amplify the voltage output.
How do you decide KVAR rating of capacitor bank?
Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs with the load variation.If we know load factor multiply it by the sine angle which gives us the capacity of the cpapcity of the load bank.

What is capacitor polarized?
A polarized capacitor is one which has a polarity, positive on one terminal, negative on the other. This makes it superficially look like a battery. In use, the capacitor has its positive voltage always higher than that on the negative terminal, it matters that this is the case and this gives rise to the term polarized. This sort of capacitor is commonly found in power supply filters.
Why is a common collector used in the last stage of the amplifier?
becoz it gives good gain which is necessary for an amplifier.
What is Coefficient of coupling?
It is a measure of how close is a coupling between two coils it gives an idea of wat portion of the flux produced by one coil links with the other coil
Why common emitter amplifier gives phase reversal?
A: Because it is a voltage amplifier the current will inversely reflect the voltage across a resistor

Only a flux capacitor and a bolt of lightning!
What is a non polarized capacitor?
A polarized capacitor is one which has a polarity, positive on one terminal, negative on the other. This makes it superficially look like a battery. In use, the capacitor has its positive voltage always higher than that on the negative terminal, it matters that this is the case and this gives rise to the term polarized.
