Question 1 (2 points) A straight wire is along a rectangular frame with a velocity i to the left in region with a constant magnetic field. The induced current in the wire is: a) Zero b) Pointing up in the drawing c) Pointing down in the drawing d) None of the above DE Question 2 (2 points) The change in electric flux: a) is proportional to the velocity of electrons b) is equivalent to the change in the electric field c) is the net rate at which charge moves past a point d) is the source of the displacement current Question 3 (2 points) The capacitance between two parallel plates depends on: a) the electric field between the plates b) the charge that builds up on the surface of the plates for a given applied voltage c) the voltage applied across them d) the area of the plates and their relative distance Question 4 (2 points) An alternating EMF with driving frequency Wa is applied to a given RLC circuit. The largest possible current for the circuit occurs if: a) Wa is large b) wa matches the natural angular frequency for the LC oscillations c) Wa is small d) wa matches the frequency of household power, roughly 60 Hz Question 5 (2 points) The inductance of an object depends on: a) the magnetic field it produces b) the current passing through it c) what other components are in the circuit d) the size and shape of the object
