1-
Suppose you are looking into one end of a long cylindrical tubein which there is a uniform electric field, pointing away from you.If the magnitude of the field is decreasing with time the fieldlines of the induced magnetic field are:
A) circles
B) ellipses
C) straight lines parallel to the electric field
D) straight lines perpendicular to the electric field
E) none of the above
2-
When the amplitude of the oscillator in a series RLC circuit isdoubled:
A) the impedance is doubled
B) the voltage across the capacitor is halved
C) the capacitive reactance is halved
D) the power factor is doubled
E) the current amplitude is doubled
