Why you use parallel resonance circuit instead of series resonance circuit in tuned voltage amplifier?
At resonance...a parallel tank circuit matches the applied sine voltage so close that there is almost 0 current flow from the source...i.e., max impedance at resonance...the capacitor and inductor are swapping energy with each other in tune with the source...
visualize it...in order to have 0 current flow for an incoming varying voltage...that would mean that the tank voltage would be varying exactly at the same frequency and voltage!
Thus...you have effectively "tuned" into a voltage which would be critical in 'tuned' voltage amplifier...
A series resonant circuit does not tune into a voltage...in fact at resonance the voltage across the inductor capacitor will be 0!...a short or minimum impedance condition
Of course my discussion assumed ideal components...in the real world there will be 'stray' resistances which will alter the results in magnitude to the size of the resistance...
Hope this helps

To find the current in a complex circuit it is necessary to know?
the source voltage and the total impedanceAnswerA 'complex circuit' describes a category of circuit that is neither series, parallel, nor series-parallel. A relatively-simple example of a complex circuit is a Wheatstone Bridge. You cannot analyse or resolve a complex circuit using the techniques used to analyse and resolve series, parallel, or series-parallel circuit. Instead you must use one or other of the various electrical theorems. For example, to determine the currents flowing in a Wheatstone Bridge circuit, you could use Kirchhoff's Laws or Thevenin's Theorem.
Power gain of an amplifier having input gain of 20W and what is the output gain of 20mW?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
Would a multimeter connected in parallel as part of the circuit measure current or power consumption or voltage or wattage?
A typical multimeter measures voltage and resistance "in parallel" or current in-line with the circuit. It all depends on the model. 'Multi' means many different modes. Some have more than others. Some multimeters can measure current, but require you to alter the lead configuration and plug into different sockets. If you have the meter set for Current measurement and you put it in parallel instead of series, it will cause a dead short and could damage the meter. (They usually have a fuse inside for protection). Knowing any two of the three parameters you can calculate the third by Ohm's Law: Voltage = Current x Resistance. Knowing Current and Voltage you can calculate power as Volts x Amps = Watts for resistance loads.
Why do scientists use schematic circuit diagrams instead of drawing a picture?
It is a lot easier and quicker. Especially if scientists cannot draw (like me)
What is short circuit?
Short circuit is the case when electricity, instead of travel through the design circuit path, jump across an unintended low resistance path and bypass the design circuit.A short circuit is a path for an electric current to travel through where there is very little resistance. This path is often, but not always, through a wire connected directly to a ground, and is often, but not always, unintentional.
What evidence from this passage could support the idea that a strand of light might benefit from using a parallel circuit instead of a series circuit?
No
How can an ammeter cause a short circuit?
An ammeter can cause a short circuit if it is connected in parallel instead of in series with the circuit being measured. This can create a low resistance path for the current to flow, bypassing the intended circuit and causing a short circuit.
What is the output impedance of common source amplifier circuit?
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
What is a complex circuits?
A 'complex circuit' is a category of electric circuit that encompasses any circuit that is not just a series circuit, a parallel circuit, or a series-parallel circuit. An example of a complex circuit is a bridge circuit.As you can see, such circuits are not necessarily complicated themselves; its just that they cannot be analyzed using only ohm's law and the power formula, but instead require more complicated methods like Theveninization, Kirchhoff's laws, etc. to be analyzed correctly.

What is Miller's Theorem?
Milller's Theorem is used to simplify a circuit for circuit analysis. Instead of one impedance, which connectes two non-grounded nodes, Miller's Theorem allows this impedance to be broken down into two parallel impedances. One impedance can be seen as Z/(1-A) and the other impedance can be simplified to Z/(1-(1/A)). In this case, Z was the value of the original impedance, and A is the gain of the amplifier being analyzed.
What is the problem when you have 110-120 volt but when circuit is completed voltage drops to 30 volts?
A resistance in series with the circuit. It is most likely a wiring error, loose connection or load hooked in series instead of parallel.
What would be the purpose of a headphone amplifier?
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
What is difference between transistor and amplifier?
A transistor is an electronic component. By itself it has little use. An amplifier is a complete, functional circuit, generally made up of several components. A transistor can be a component part of an amplifier, however an amplifier may be constructed without any transistors (using vacuum tubes instead, for instance).
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
Should a fuse be in a series or a parallel circuit with the main power coming into a house?
i think a fuse should be in a parallel circuit with the main power because if something from your house turns off you can go look in the fuse box instead of every single one being alone that's what i think(p.s who's is better mine or the one that just said series's)
Can parallel circuits be used instead of fuses?
No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
