Configuring op-amp to supply constant current

AI Thread Summary
An op-amp can be configured to supply a constant current to a load by using feedback to regulate the output based on the load's resistance changes. The feedback mechanism allows the op-amp to adjust its output to maintain a consistent current, regardless of variations in load resistance. Understanding the principles of feedback in op-amp circuits is crucial for achieving this constant current supply. The discussion highlights the need for a foundational knowledge of electronics to effectively implement such a configuration. Properly setting up the feedback path is essential for maintaining the desired current output.

Homework Statement



How could an op-amp with feedback be configured so that it would supply a constant current to some load, even if the resistance of the load changed?

Homework Equations



None. Just a general question.

The Attempt at a Solution



I don't really know how to approach this as I don't have a huge amount of knowledge of electronics.

If you want something held constant it usually needs to participate in the feedback path in some way...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
