PHYS 122 Midterm: PHY122A UW Exam 2
Document Summary
Name _____________________________________ total ___________ (last, first) phys 122a: [25 points] a loop of wire, of length a=1m and width b=3cm, is shown at left. There is a magnetic field, pointing out of the page, The loop of wire is pulled to the left at a steady speed of v=3m/s. [25 points] in the circuit shown, an inductor and resistor are connected in parallel, which are then connected in series with another resister, a switch, and a battery. Both resisters are r=5 , the battery is v=10v, and the inductor is l=3h. Consider the battery and the inductor to be ideal (that is, they have no internal resistance): [4 pts] at t=0 the switch closes. [25 points] the coaxial cable, shown, has a uniform inner copper conductor of radius a=1mm and the inner radius of the outer conducting copper shell is b=3mm. The inner conductor carries a charge of 3 c/m, and the outer conductor 3 c/m.
