Open loop gain of an operational amplifier

AI Thread Summary
To experimentally determine the open loop voltage gain of an operational amplifier with AC input voltage, ensure the inputs are at the same voltage when no input signal is present. This can be achieved by using feedback at DC to stabilize the inputs without introducing AC feedback. The supply voltage for the op-amp is +9V, which is crucial for its operation. The process involves careful measurement and control of input conditions to accurately assess the gain. Understanding these principles is essential for conducting the experiment successfully.

The Attempt at a Solution



I'm really stuck here. I would appreciate some outline of basically what I have to do so I could even make a first attempt at this.

An opamp has a very large gain with a DC input, so you must make sure the inputs
are at the same voltage if there's no input signal.

Use feedback to do this at DC without producing AC feedback.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
