Increasing the number of turns in the coil Increasing the strength of the current Increasing the area of cross-section of the coil Increasing the strength of the radial magnetic field..

Therefore the non-resistive of a coil to a.c. due to the varying magnetic field is called capacitive reactance Xc. Unit of Xc is also Ohm The current leads the EMF by 90 o and the phasor diagram is: For DC, Xc becomes infinite and hence, capacitance block DC flowing through i..
