Thank you for taking the time to answer! :smile: I appreciate it!

resistance = resistivity * length / area well it is obvious that the resistance will increase when using a longer wire. length = N * (μ0 * I)/B is it right to say that"double N" gives us "double length" here? if so it is, then R2 = 2R1 and the time constant will be two times longer. Am I...

Is my solution reasonable? What I got from my first attempt is that the time constant won't change. WHY? Because when we double the number of loops (N) we're going to have new values for both the self inductance and the resistance of the solenoid and so the ratio (L/R) stays the same. Here is a...

Thank you for your reply. I did as you told me and I think it seems reasonable. Here is a photo of the solution.

Hello! It says that the Time Constant of an RC circuit is equal to 100 ms. What is the energy that remains in the circuit after 300 ms? "Nothing mentioned about whether it is in falling or rising edge". The formulas that I have been using are : W = 0,5 (C* V^2) V = V0 ( e^-t/rc ) since I don't...
