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

Ответ:
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![X_L](/tpl/images/0410/9917/8c92c.png)
L= 0.10024 H
L = 100.24 mH
This is the inductance .
