Lab 6 Faraday's Law Exercise
The 60 Hz sinusoidal voltages contained in Table 1 were applied to the inductor shown in Figure 1.
Recall for an inductor,
The ratio of the voltage amplitude to the current amplitude is,
(1)
If,
then,
(2)
where the inductance, L is,
(3)
where _{} is the permeability of the core material, N is the number of turns, A is the cross-sectional area of the core, and l is the length of the flux path.
