Name two ways to increase the current to a load?
1) Use an operational amplifier.2) If voltage is not an issue, a transformer may be used.
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.
What is an instrumentation amplifier used for?
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier signal.
Why ujt used as an oscillator?
why ujt used as amplifier
What are the industrial applications of integrator and differentiator circuits using operational amplifier?
differentiator is used in t.v.
What amplifier circuit is typically used as the input stage for an operational amplifier?
Differential amplifier ANSWER: A differential amplifier is an op amp. If any amplification is required a preamplifier is used mainly to cut the white noise and improve the input impedance
Why is an inductor used for?
what is an inductor used for
Why 741 number is used in opamp741?
741 is pin no of operational amplifier that's why the no 741 has been given to opamp741
Can operational amplifier be used to sum or more signals?
A: Sure by adding or subtracting from different inputs or scaling with different value of resistors
Name two ways to increase the current to a load?

What are the two basic configurations in operational amplifier?
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
How an operational amplifier can amplify DC signals?
It takes the difference between of two input and amplify by the open loop gain of the amplifier or closed loop gain of the amplifier. It is very hard to control open loop gain of 100 Db so it very seldom used
Why inductor are used in CKT?
inductor is used in ckt because it will work as controling current device
Could you briefly explain the applications of FET?
Due to its *low noise *high input impedence and low output impedence FET is used in numerous applications. *Buffer ampliier *Phase shift oscillator *Integrator *Amplifier
What is single tuned voltage amplifier?
it is a circuit consisting of a tuned circuit with a capacitor in parallel with inductor and it is connected to collector terminal in common emitter configuration,, and it is used as frequency receiver
What is the origin of the name operational amplifier?
In the old days, Op Amps were used in analog computers to perform mathematical 'operations', such as summing, differentiation, integration etc. Hence the name.
