Chapter 21, Problem 48P

(a)

To determine

The resistance of the solenoid, if it is made from a 100 m copper wire with cross-sectional area $0.2{\text{ mm}}^2$ and resistivity $1.7\times {10}^{-8}\Omega \cdot \text{m}$. The wire is wound on a plastic tube with 780 turns, having a diameter of 4.0 cm and a length of 10.0 cm.

(b)

To determine

The inductance of the solenoid, if it is made from a 100 m copper wire with cross-sectional area $0.2{\text{ mm}}^2$ and resistivity $1.7\times {10}^{-8}\Omega \cdot \text{m}$. The wire is wound on a plastic tube with 780-turns, having a diameter of 4.0 cm and a length of 10.0 cm.

(c)

To determine

The frequency of the alternating current at which the inductive reactance of the solenoid is equal to its resistance, if it is made from a 100 m copper wire with cross-sectional area $0.2{\text{ mm}}^2$ and resistivity $1.7\times {10}^{-8}\Omega \cdot \text{m}$. The wire is wound on a plastic tube with 780-turns, having a diameter of 4.0 cm and a length of 10.0 cm.
