Filter chokes are rated according to:

Which of the following circuits gives the best regulation, under similar load conditions?

The advantage of the capacitor input filter over the choke input filter is:

With a normal load, the choke input filter will give the:

There are two types of filters in general use in a power supply. They are called:

The main function of the bleeder resistor in a power supply is to provide a discharge path for the capacitor in the power supply. But it may also be used for a secondary function, which is to:

In a power supply, series chokes will:

When using a choke input filter, a minimum current should be drawn all the time when the device is switched on. This can be accomplished by:

In the design of a power supply, the designer must be careful of resonance effects because the ripple voltage could build up to a high value. The components that must be carefully selected are:

Excessive rectifier peak current and abnormally high peak inverse voltages can be caused in a power supply by the filter forming a:

In a properly designed choke input filter power supply, the filter capacitor will be about nine-tenths of the AC RMS noload voltage across the voltage; yet it is advisable to use capacitors rated at the peak transformer voltage. Why is this large safety margin suggested?
