Why use inductors in transistor amplifier circuit?
Audio power amplifiers usually separate the last inductor in the output stage transmission chain. The last inductor usually receives the most attention when it comes to power efficiency in a circuit. Since circuits experience opposition to current, especially where current is changing direction, capacitive reactance or opposition needs to be balanced with inductive reactance. This is done with the help of an output inductor for maximum output to be reached. Output inductors are used to dampen circuit resonance with the help of a shunt resistor. This is especially important in high frequency circuits where stability is a real issue.
The total opposition to current in a series RC circuit is called?
Assuming you are talking about an AC circuit, then the total opposition to the flow of current in an R-C circuit is called its impedance (symbol: Z), measured in ohms. This is the vector sum of the circuit's resistance (R) and its capacitive reactance (XC) -each also measured in ohms.
What type of inductor is installed in a circuit to impede the flow of ac of a frequency?
A: The inductor is called a RF choke
What is the unit to measure the opposition to the flow of electrical current called?
Answer: Inductive reactance is the opposition to the change in current in an electrical circuit and is abbreviated Xl. Answer: The opposition to current flow is called resistance (for DC), or impedance (for AC; often just called resistance); the unit for both is the ohm.
Inductors and its types?
INDUCTORS are a type of passive electrical devices that are used to store energy from magnetic fields and release it when needed.The electronic component(mostly a coil) which opposes the changes in current in circuit is called an inductor . The ablitity to oppose the change of current flowing through is it is called inductance of the coil / inductor .The inductance of an inductor may also be defined as ablity to produce induced voltage when current varies through it .
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What is the opposition to flow of current in a circuit called?
The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
The total opposition to an alternating current presented by a circuit is called a?
impedance

Total opposition to current flow in an AC circuit with both resistance and reactance is called?
Impedance.

Why is the parallel resonant circuit called an rejector circuit?
THE PARALLEL rlc CIRCUIT IS CALLED A REJECTOR CIRCUIT BECAUSE IT REJECTS DOWN THE CURRENT. THE REASON IS AT RESONANCE THE IMPEDENCE OF THE CAPACITOR BECOMES EQUAL TO THAT OF THE INDUCTOR SO NO CURRENT FLOWS. AT LOW FREQUENCY THE CAPACITIVE REACTANCE IS LOW SO ALL THE CURRENT FLOWS THROUGH THE INDUCTOR AND WHEN THE FREQUENCY IS HIGH ALL THE CURRENT WILL FLOW THROUGH THE CAPACITOR BECAUSE AT THAT POINT THE REACTANCE OF THE CAPACITOR IS LOW. SO WE OBTAIN A V-SHAPED GRAPH WITH THE PEAK OF V INDICATING THE REJECTION OF CURRENT.

The opposition of current is called?
"Opposition to current" can refer to resistance, reactance, or impedance.

What is the heat produced by an inductor?
They are called I squared R losses. That is the formula for calculating power (P) in watts. P=I^2*R. I equals current in amps. R equals resistance in ohms. Also if the voltage (E) is known the formula is P=E^2/R. The current of electrons meets the resistance of the coil wire. That results in heat in inductor and transformer coils.
