The inductor's resistance, R, is 1550.38.

1.05 H is the inductance L.

What distinguishes an inductor from a capacitor?

A capacitance opposes a variation in voltage, while an inductance opposes a changes in current. This is one of the key distinctions between the two components. Additionally, the capacitor and inductor both store energies with in type of either a magnetic charge and a magnetic force, respectively.

Briefing-

Given:

Emf, E=15.5V

Current, i = 4.86mA

Time, t = 0.940 ms

Maximum current, imax Calculation: 6.45mA

a) The resistance is given by,

Ꭱ= V/Imax = 10/6.45×10⁻³= 1550.38Ω

b) The inductance is given by,

L= -Rt/(1-i/imax)= 1550.38×0.940×10⁻³/In(1-4.86/6.45)

The inductance L is 1.05 H.
