Op amps have multistages. Each stage will contribute atleast a pole to the system. The effective effect of these poles will result in instability of system due to

What are the three factors that effect the electrical parameters of a op-amp?
Supply voltage , temperature , frequency are factors that effect the electrical parameters of opamp
IC 741 is an?
It is an opamp chip consisting of 8 pins
What is the output when both the inverting and non inverting terminal of opamp is on same voltage in open loop configuration?
Ideally, the output voltage should be zero when the two inputs are equal to each other. Generally, an offset null adjustment is provided to do that - you short the two inputs together, and adjust the null for zero output. You just have to be careful, because high performance op-amps can "see" even the short sections of wire used for the jumper and treat that as an inductor, creating an RF oscillator. High frequency rolloff compensation usually is added to prevent this.
Why it is desirable for an op amp to have a high CMRR?
A high CMRR prevents the opamp from passing undesirable common mode signals.
What is the need of under frequency relay in load shedding on power system?
when the load on a certain system increases the frequency of the system falls normally. It is dangerous to operate the equipments when the frequency is lower than the normal rated frequency so shed the when the frequency falls under voltage relays are used. I hope i answered your question :)

What is frequency compensation?
Frequency compensation is a technique used in amplifiers. It basically controls the sound of the amplifier to make it sound clear and free of positive feedback.
Similarity between opamp and comparator?
A comparator is simply an opamp with a certain configuation of external circuitry ( a few components) that make it function as a comparator.
How gain varies with bandwidth in an op-amp?
The gain of an op amp varies with frequency. After an op amp reaches the half-power point, the gain falls appreciably. And then once it hits the transition frequency, the op amp no longer provides any gain.
Do you need a license to apply eyelash extensions in Florida?
Yes and No. You do need one if you are receiving "compensation. You do not need one if you are NOT receiving "compensation.
Is IC741 a hybrid ic?
no, the 741 opamp is a monolithic IC.
IC 741 is an?
It is an opamp chip consisting of 8 pins
Why voltage gain is high in op amp?
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
Objectives of compensation?
You need to include in the statement what type of compensation you are expecting. You may also include the amount of compensation you have received in the past.
Where is the ground on an operational amplifier?
An opamp has a ground terminal on one of the pins.
What is the advantage of bistable multivibrator using 555 ic over those made with opamp or bjt?
The advantage is most of the circuit has already been connected up for you and you only have to add a dc power supply and couple of components to set what frequency you want it to work at.
Why Need for carrier frequency stability?
Explain the need for carrier frequency stability in radio transmitters?
