As a way of determining the inductance of a coil used in a research project, a student first connects the coil to a 11.5 v battery and measures a current of 0.620 a. the student then connects the coil to a 24.0 v (rms), 60.0 hz generator and measures an rms current of 0.570 a. what is the inductance? l = mh

L = 100.24 mH

Explanation:

Given that

V= 11.5 V

I= 0.62 A

V(rms) = 24 V

f= 60 Hz

I(rms) = 0.57 A

resistance R

V= I R

11.5 = 0.62 R

R= 18.54 ohm

impedance Z given

V(rms) =  I(rms) Z

24 = 0.57 Z  ,Z= 42.10 ohm

inductor  impedance  

L= 0.10024 H

L = 100.24 mH

This is the inductance .
