The figure shows a half-wave rectifier with a 475 µF filter capacitor. The load draws a constant current I0= 1 A from the rectifier. The figure also shows the input voltage Vi , the output voltage VC and the peak-to-peak voltage ripple on VC.The input voltage Vi is a triangle-wave with an amplitude of 10 V and a period of 1 ms.  The value of the ripple u (in volts) is ______________.
