In the fixed.bias biasing several key parameters of the amplifier depend on the Beta of the transistor. This parameter has a wide variation (often 5 to 1 or more) for a particular transistor type. Thus, if you need to make a production run of a number of identical amplifiers, this variation in the Beta is unacceptable.
In the voltage-divider stabilized method the performance of the amplifier is independent of Beta (or almost). Thus, this design is suitable to be used in the production of a large number of identical devices.
In terms of biasing, a voltage divider circuit helps offset the effect of changes in the beta value of the transistor. So it's said to be more 'stable' because heating of the transistor, or swapping transistors entirely (both of which affect beta) will not greatly affect the output of the circuit.
As far as the actual output is concerned, I believe both circuits have similar input/output impedance ranges and similar voltage gains. But the fixed biased circuit typically has more current gain.
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
To get reasonable gain without losing stability of circuit. ANSWER: Is to reduce the input to a lesser value or to match signals impedance
_____________ J| -_____/\/\/\/\_________+ | | | - + | |___i|i|___| E Well this is the circuit diagram , where r is the sliding jockey of the rheostat and a cell (E) is connected in parallel with the rheostat. By adjusting the jockey resistance of the rheostat can be altered which in turn would regulate the potential offered by the cell E to the main circuit. And thus a rheostat can be used as a potential divider.
4017 IC is a counter, divider integrated circuit. It is a decade counter that has 10 different decode outputs and is commonly called a CMOS.
When we want to regulate somthing ;we use variable resistors for example :volume control in radios and volume in headset. Also , the variable resistors can forms a potential devider in which the overall resistance between the two end points remain the same,but the ratio of the two resistors in the legs changes.so the variable resistor is affectively a potential divider. Also, the variable resistor can forms a potential divider in which the overall resistance between the two end points remains the same, but the ratio of the two resistors in the legs changes. So, the variable resistor is effectively a potential divider.
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
The essential circuit of a voltage divider, also called a potential divider, is:
A: that is true for less current a divider is OK it has to do with the series resistance and loading if the loading is forever fixed and the source is also fixed at a value then a divider can be used no matter what the current is.
Thevenization of the divider circuit will help you see how it operates.
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
its the same
a divider
you can use a voltage divider or a step-down transformer to lower voltage.
To get reasonable gain without losing stability of circuit. ANSWER: Is to reduce the input to a lesser value or to match signals impedance
it means u have benn rapped
The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.
it depends on the type of the circuit you are analyzing..it could be a voltage divider, emitter follower, be specific on what type of circuit and maybe i can help you aobut this question.
