Q & A
Q:  What is self-switching power supply unit (PSU)?
A:  When load is present it automatically switches on the supply otherwise it goes off.
Q:  What is the load used?
A:  12V, 6W incandescent lamp is used
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

we referred this website,while searching the projects related to DC motors.
Because we studied the website and whatever the information we need,that’s applicable here itself,we liked video explanation a lot.
I and my friends purchase it through online.
