Titanium is a reasonably good conductor. A student wants to create an 8.00 mH inductor using titanium wire. To do this, the student wraps the wire into the shape of a solenoid with radius 12.0 mm and length 1.50 cm. This means the student needs 460 turns of wire wrapped around this solenoid. The student uses very thin 28 AWG wire which has a diameter of 0.320 mm. The resulting inductor uses so much wire that it has a resistance...
