Homework Statement
Homework Equations
The Attempt at a Solution
Self inductance L of a solenoid = μN2S/l
N = Total number of turns
l = Length of the solenoid
S = Cross sectional area of the solenoid
From the language of the problem statement I am assuming that S and N of the two solenoids are same .This makes" l " different for the two solenoids .
Self inductance L will be different .
This means for equal currents magnetic potential energy will also be different .
Now since the two solenoids are of different lengths and diameter of the wires are also different , resistance of the two coils will also be different .This means for equal currents , power dissipated will also be different .
Since both L and R are different , then time constant will also be different .
So to me it looks like all the statements are correct i.e option 4)
Is that correct ?
