What is inverting and non inverting mode of op amp explain?
Inverting and non-inverting modes refer to the two primary configurations of an operational amplifier (op-amp). In the inverting mode, the input signal is applied to the inverting terminal (negative input), resulting in an output that is 180 degrees out of phase with the input, with a gain determined by external resistors. Conversely, in the non-inverting mode, the input signal is applied to the non-inverting terminal (positive input), producing an output that is in phase with the input and has a gain greater than one, also determined by external resistors. Both configurations leverage the op-amp's ability to amplify voltage signals while providing different phase relationships and gain characteristics.
When you daisy chain two amplifiers how do you determine the combined output?
If one amplifier has its own feedback then that will be its gain witch can be added to the next amplifier gain. if both amplifier have a common feedback then that will be to total gain for both.

What is voltage offset?
Input offset voltage is the equivalent voltage at the input of an operational amplifier. If an amplifier has a voltage gain of ten and an input offset voltage of 10 microvolts, a level of 100 microvolts will appear at the output with no input. Manufacturers try to design an op amp so the input offset voltage is as small as possible to minimize this error voltage at the output of the amplifier, especially for applications where small voltages are being amplified.
What are the two basic configurations of pianos?
The two basic configurations of pianos are upright and grand. There is also the baby grand, which is a type of grand.
Difference between instrumentation and operational amplifiers?
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
Why a triangle symbol for an operational amplifier?
Why not? It has two inputs and one output. So a triangle that can accomidate two intputs and one output is perfect!
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.
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
How does an Operational Amp work?
An operational amplifier is an extremely high gain differential voltage amplifier--a device that compares the voltages of two inputs and produces an output voltage that's many times the difference between their voltages. How the operational amplifier performs this subtraction and multiplication process depends on the type of operational amplifier, but in most cases two input voltages control how current is shared between two paths of a parallel circuit. Even a tiny difference between the input voltages produces a large current difference in the two paths--the path that's controlled by the higher voltage input carries a much larger current than the other path. The imbalance in currents between the two paths produces significant voltage differences in their components and these voltage differences are again compared in a second stage of differential voltage amplification. Eventually the differences in currents and voltage become quite large and a final amplifier stage is used to produce either a large positive output voltage or a large negative output voltage, depending on which input has the higher voltage. In a typical application, feedback is used to keep the two input voltages very close to one another, so that the output voltage actually falls in between its two extremes. At that operating point, the operational amplifier is exquisitely sensitive to even the tiniest changes in its input voltages and makes a wonderful amplifier for small electric signals.
What would you use an op-amp for?
You would certainly use an op-amp or an operational amplifier, if two opposite sides which successfully met and made operations correctly with no bugs.
What is an inverse amplifier?
An inverse amplifier, commonly known as an inverting amplifier, is a type of operational amplifier (op-amp) configuration that produces an output voltage that is inversely proportional to the input voltage. This means that if the input voltage increases, the output voltage decreases, and vice versa. The gain of the inverting amplifier is determined by the ratio of two resistors in the feedback and input paths. It is widely used in various applications including signal processing and analog computing.

How does a jfet input operational amplifier work?
A: an operational amplifier has two input A+ and a - input feeding to a base of a transistor ideally both diodes are matched with a current source to make them equal so basically they are both balanced or virtually at the same potential increasing one potential to one will inversely effect the other. usually these junctions are transistor base to emitter but it could that one is just a plain diode working on the exponential curve of the diodes
