A variable inductor with negligible resistance is connected to an ac voltage source. By what factor does the current in the inductor decrease if the inductance is increased by a factor of 2.0 and the driving frequency is increased by a factor of 6.0? ? x
Inductive reactance X(L) wL Current I voltage V/X(L) With the given increases, X(L) is multiplied by 12, so I decreases to 1/12 its initial value.
