How do you improve open loop system?
Feedback from the output to the input will provide stability and control. It is desirable to havemaximum open loop gain but without proper feedback it will be probably totally unstable
What is use of spike buster in relay?
A: I never heard of a spike buster but if you are from England I would understand the different terminology. The use for the spike buster is to protect the driving circuit from negative spikes generated by the relay coil as it releases the power stored in it. The DIODE [ SPIKE BUSTER] will clamp harmlessly the negative spike to .6 to .7v negative which will harm the driving circuit Without the diode hundreds of volts can be generated destroying the driving circuit
What is the difference between oscillator and multivibrators?
Oscillator is an electronic circuit which can generate oscillating sin signal without any oscillating input with use of positive feedback Multivibrator is a two stage RC coupled amplifier circuit which can generate squae signal without ac input
What is the logic behind flow of electricity without circuit?
current
How does a transistor act as a oscillator?
A: actually any active components will oscillate with positive feedback A transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit has a natural resonant frequency, meaning the L and C together will try to generate a specific frequency; this is then fed back into the input of the transistor amplifier, and the output is fed to the LC tank circuit exacerbating this oscillation until it reaches its' maximum level. An inverting amplifier can be used similarly; the output is fed to the input; this will cause the output to change as fast as the amplifier can. The frequency of this design is much harder to control, but potentially higher. Also, without the LC tank, the output voltage will remain lower.
Is opamp a linear device?
A: It should be that is the normal operating mode. To be linear it strongly depends on negative feedback to maintain it into that linear region. By itself without any feedback it is very unstable due to the hi gain open loop availability

How are negative and positive feedback involved in homeostatic regulation?
Negative feedback occurs when the output of a system reacts to cancel out the effects of an input of a system, as opposed to positive feedback (in which the actions/output is intensified or increased). The more negative, the more stable. Thus, with things being canceled out, the body maintains homeostasis. An example of negative feedback in action is the maintenance of blood glucose levels and body temperature. With input of sugar, insulin is released to stabilize the body (on the other hand, without insulin, diabetes can be diagnosed). With a raise in body temperature, blood vessels and pores are opened to release heat.
Is it impossible to keep your body chemistry in balance without some sort of negative feedback mechanism?
Negative feedback mechanisms are essential for maintaining homeostasis in the body by responding to changes and restoring equilibrium. Without these mechanisms, it would be challenging to regulate functions such as temperature, pH levels, and hormone levels, leading to potential imbalances and health issues. Thus, negative feedback mechanisms play a crucial role in keeping the body's chemistry in balance.
Can the car run without the negative terminal connected?
The negative teminal needs to be connected to complete the electrical circuit. Without that none of the electronics in the vehicle will work, including the starter.
Why is feedback useful?
So u can understand the subject/person better
Why is there a positive and a negative in a car battery?
Because you won't get a complete and closed circuit without a ground.
What is the importance of negative feedback in the control of vasodilation and vasoconstriction?
Vasoconstriction and Vasodilation are a part of a body negative feedback, in which the body tries to restore homeostasis. Homeostatis is the function of keeping the internal body at it's general temperature (37 degrees Celsius). Without the negative feedback of Vasoconstriction and Vasodilation, the body would either be at a very low or very high temperature and this high/low temperature could cause death.
What is thermal stability of transistor?
The thermal stability is the ability of the transistor to withstand changes in temperature without the transistor's parameters changing. Transistors generally have poor thermal stability and in particular the Beta parameter increases with temperaure, which can cause thermal runaway in a badly designed circuit. This is well known and the bias current in transistors is normally stabilised by the application of negative feedback in proper circuit design.
What do you think would happen to the level of a hormone in the blood if negative feedback didn't happen?
If negative feedback did not occur, the hormone level in the blood would likely continue to increase. Negative feedback mechanisms control hormones by signaling the body to stop producing them once they reach a certain level. Without this regulation, hormone levels could become dangerously high or low, leading to health issues.
Can you have a viable system without feedback?
A system requires feedback to fix out bugs and errors made by the developer, your system can be viable without feedback however getting feedback is recommended
What is the need of regulation in electronic circuit?
A: Regulation is a term describing means and ways to control either voltage or current. On an analogue circuit feedback circuitry are implemented to decrease the output to compensate for an increase in input. on digital regulators again feedback is used to modify a pulse duty cycle to compensate for the same thing.
