Question

Consider the large inductor in Figure 3 with given number of turns N, core permeability μ, core cross section area A, and core diameter are given. Note that the core length l is equal to π times the core diameter. Answer the questions and pick an answer from the given choices.

The coil is made up of copper wire that has a cross section area of 1 cm², and the length of each turn is nearly equal to 1 m. Find the resistance of the coil. (Assume an operating temperature of 20^o C).

1) 180.2 mΩ

2) 17.2 mΩ

3) 1.2 Ω

4) 850.5 mΩ
