Estimate the inductance l of a coil that is 12 cm long, made of about 235 copper-wire turns and a diameter of about 1.7 cm. show work and units. compare your answer to the nominal value here 78+- 22mh

Inductance as calculated is 13.12 mH

Solution:

As per the question:

Length of the coil, l = 12 cm = 0.12 m

Diameter, d = 1.7 cm = 0.017 m

No. of turns, N = 235

Now,

Area of cross-section of the wire, A =

We know that the inductance of the coil is given by the formula:

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.
