What is the maximum value of the current through the inductor?

Click For Summary

Homework Help Overview

The discussion revolves around a circuit involving two identical uncharged capacitors and an inductor, focusing on the maximum current through the inductor after a series of switch operations. The problem is situated within the context of electrical circuits and oscillatory behavior in inductive-capacitive systems.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the application of Kirchhoff's loop rule and the relationships between charge and current in the circuit. There are attempts to derive equations for current and charge at specific times, with some questioning the assignment of signs in their equations. Others discuss the implications of the switch operations on the circuit's behavior.

Discussion Status

The discussion is ongoing, with participants providing guidance on the correct application of circuit principles and questioning assumptions about the configuration of capacitors. There is a recognition of the complexity introduced by simultaneous switch operations and the need for careful consideration of charge distribution and potential differences.

Contextual Notes

Participants note potential confusion regarding the series or parallel arrangement of capacitors based on their charge assignments and the implications of switch operations on the circuit's energy dynamics. There is an acknowledgment of the challenges in managing instantaneous changes in the circuit configuration.

Whoops... my mistake :oops:. Your answer in post #27 was correct.

But answer is not matching. They say its 380/13 for capacitor C3.[emoji27]

40, 30, 10 are the potential difference applied to charge the capacitros, not the charge itself.
Good point.. but then, for C1, 40*2=?

i am so sorry, it will be 80 and I have written 60. I am so sorry...I have got the answer now...I have this exam in a week and i don't know what will happen if i do mistakes like this. Thank you sir for your patience and helping me out. And also for reminding me of this concept. Thank you so much.

There's no need to apologise to me. I made mistakes too on this one.
