How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
What does a jack do in an amplifier circuit?
A jack is a connector socket designed for the insertion of a plug. The plug can connect input, output, or auxiliary devices to the amplifier circuit.
What should be the value of capacitor at transistor amplifier circuit input?
at full input, if the transistor is working, the value of capacitor will be 0.
How does the non inverting amplifier differs from voltage follower circuit?
altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.
The voltage gain of an inverting operational amplifier with negative feedback is controlled by the ratio of?
The series input resistor and the feedback resistor.
Why a high input impedance?
A circuit (an amplifier) typically has a high input impedance so that it does not unduly load the input circuit. Any such load could cause distortion, and that is generally not desired.
What is buffer amplifier and its applications?
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
How do you use an instrumentation amplifier as a temperature indicator?
You use a thermocouple as the input to the amplifier circuit.
What does the OP stand for in OP amps?
Op amps stands for operational amplifier. An operational amplifiers is a high gain voltage amplifier that requires a differential input and produces single outputs.
What are the applications of fixed bias amplifier circuit?
low input impedance
What does a jack do in an amplifier circuit?

What does a comparator do in electronics?
A comparator is an operational amplifier used without a feedback circuit. The output of the comparator will be high when the voltage of the non-inverting input is below the inverting input, and low when the inverting is above the non-inverting input. The output is undefined - i.e. can by anything - when the voltages are equal.
Can you amplify DC voltages?
Yes, certainly - an operational amplifier circuit (see e.g. Wikipedia) will do this. For instance, a non-inverting amplifier circuit with a gain of 10 will give 1.0V output for 100mV input, 2.0V for 200mV, and so on (limited by the supply voltage of the amplifier). Physical sensors such as thermocouples or strain gauges often need DC amplification to make their outputs easier to measure.
Circuit diagram of RC coupled amplifier?
One of the several uses of an RC coupled amplifier is to amplify the given input signal. It makes use of a sinusoidal input signal.
What is amplifier and oscillator?
amplifier is electronic circuit which is used to increase the amplitude of the input signal without affecting its frequency and phase.
