Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Does the capacitor coupling gives the higher gain in case of amplifier?
NO. Transformer coupling gives the higher gain in case of amplifer.
Why transformer coupled amplifier is more efficient than RC coupled amplifier?
an RC coupled amplifier is basically used for voltage amplification , where the circuit currents are quite low. higher currents & voltages would mean more dissipation in the load resistors , which is essentially very lossy . The coupling amplitude to the next stage is ideally the same as the previous stage signal excursion. However if a transformer is used for coupling , both large voltages & current can be handled without incurring the dissipation of a resistive load. Moreover a coupling gain of the transformer primary to secondary ratio is also a bonus. also because of the possiblity of correct impedance matching on the primary & secondary side maximum power coupling is obtained. hence transformer coupling is more efficient in such applications. in high frequency applications transformer coupling , along with tuned circuits as applicable is the choice circuit.
Why transformer core is of magnetic not of wooden?
The transformer core is ferromagnetic in order to focus and concentrate the magnetic fields generated in the windings. This improves coupling and increases inductance.
What is an example of mutual inductance?
A transformer because, to work, it must use mutual inductance between its separate windings.
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
What is the mutual coupling in single phase transformer?
primary winding flux links with secondary winding produses voltage across the secondary winding
Which coupling give higher gain in case of amplifier?
Transformer coupling
What are the different types of couplings?
1)rc coupling 2)transformer coupling 3)direct coupling
What is the difference between an ordinary transformer and resonant coupling energy transfer?
What is the difference between an ordinary transformer and resonant coupling energy transfer?
What are the advantages of Transformer coupling method?
transformer coupling ensures maximum power transfer is obtained even if the output impedance is not equal to the load impedance
Does the capacitor coupling gives the higher gain in case of amplifier?
NO. Transformer coupling gives the higher gain in case of amplifer.
What is the difference between transformer coupling and RC coupling?
RC COUPLING :- is the most Commonly used Coupling Between the two stages of a cascaded or multistage amplifier because it is cheaper in cost and Very compact circuit and provides excellent frequency response. TRANSFORMER COUPLING :- Impedence Coupling results in more efficient amplification because no signal power is wasted in Inductor L. Such Coupling has the drawback of being larger, Heavier and Costlier than the RC COUPLING. Impedence Coupling is rarely used beyond audio range . by : Muhammad zubair.... muet student of telecom.
