An emitter resistor helps stabilize the Q point by providing negative feedback. When the transistor's collector current increases, the voltage drop across the emitter resistor also increases, which reduces the base-emitter voltage (V_BE) and subsequently decreases the collector current. This negative feedback mechanism counteracts variations in temperature or transistor parameters, ensuring that the operating point remains stable and less susceptible to changes. As a result, the emitter resistor enhances the linearity and reliability of the amplifier circuit.

The dc input resistance of MOSFET is?
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.
What role does a resistor have that is installed in parallel to a relay coil?
A resistor installed in parallel to a relay coil serves primarily to suppress voltage spikes or back EMF generated when the relay is de-energized. This helps protect other components in the circuit from potential damage caused by the sudden release of energy stored in the coil. Additionally, the resistor can also help in controlling the relay's release time, ensuring a smoother operation.
Why is series resistor in all experiment necessary?
A series resistor is necessary in experiments to limit the current flowing through the circuit, protecting sensitive components from damage due to excessive current. It also helps to stabilize voltage levels across components, ensuring accurate measurements and consistent performance. Additionally, a series resistor can help create desired voltage drops, enabling better control of the circuit's behavior during the experiment.
What is the function of a R3 resistor?
An R3 resistor is typically used in electronic circuits to limit current, divide voltage, or set biasing levels in conjunction with other components. Its specific function can vary depending on the circuit design, but it generally helps to ensure that components operate within their safe limits and maintain desired performance. By controlling current flow, the R3 resistor can also help stabilize the operation of active devices like transistors and operational amplifiers.
How can you find a resistance of resistor without DMM explain the method with the help of example?
Hi You can find the value of the resistor by using colour code printed on the resistor. 1. Hold the resistor such that the colour code starts from left. 2. Each of the colour bands present on the resistor specifies a value. 3. The first colour band represents the first significant figure, the second band represents the second significant figure and the third band indicates the multiplier. The fourth band represents the tolerance. Gold band- 5%, Silver band-10%, No band-20% 4.Find the appropriate values for the colour by using the chart 1. 5. Find the value of the resistor by using the formula 1. Chart1 Example: Here first band represent brown. Second band represent black. Third band represent red . Fourth band represent gold. The value of resistor = 10 x 102 ± 5% = 1kΩ ± 5%
What component develops the output signal in a common emitter amplifier?
The voltage drop across the emitter-collector junction develops the output signal with the help of a resistor or two in series. The output is 'seen' at the collector.
IS there an emitter in the univeres?
There are many emitters in the universe. For example, the Sun is an emitter of electromagnetic waves and certain types of particles. It would help if you were more specific.
What are the colors of a resistor and why are they there?
There are many colours for resistor rings but the reason that we have them is to help the resistor reduce the electrical current that is passing through.
What are the muscles that help prime movers by stabilizing the movement?
Synergists
What is the resistor color code and how is it used to identify and select resistors?
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.
Where is the ignition ballast resistor on a 1988 dodge Dakota 3.9?
A 1998 Dakota does not have a ballast resistor.
Testing of resistor with the help of CRO?
yes resistor can check in CRO.Using an probes we can check it. CRO shows the waveform.
What are the installation steps for a pop-up drain emitter in a yard drainage system?
To install a pop-up drain emitter in a yard drainage system, follow these steps: Dig a hole at the end of the drainage pipe where the water will be discharged. Attach the pop-up drain emitter to the end of the pipe. Backfill the hole around the emitter, ensuring it is level with the ground. Test the system by pouring water into the drain to see if the emitter pops up and discharges water properly. Adjust the emitter as needed to ensure proper drainage. These steps will help you effectively install a pop-up drain emitter in your yard drainage system.
