A solenoid consists of 4200 turns of copper wire. The wire has a diameter of 0.200 mm. The solenoid has a diameter of 1.00 cm. When the solenoid is connected to a 12.0 V battery, we observe that the current increases over time and is 155 mA after 1.50 milliseconds have passed. Assume that the internal resistance of the battery and connecting wires is negligible.
Required:
a. What is the length of wire needed to form the solenoid?
b. What is the inductance of the solenoid?
c. What is the length of the solenoid?
d. What will be the current after three time constants have elapsed?
