Webbwhere I 0 = E 0 (1/ωC) 1/ωC = X C is the resistance offered by the capacitor. It is called capacitive reactance. Its unit is ohm. From equations (1) and (2), it follows that in an a.c. circuit with a capacitor, the current leads the voltage by a phase angle of π/2. In other words, the emf lags behind the current by a phase angle of π/2. http://physics.wm.edu/~labs/108_pdf/ch6.pdf
