The figure shows a half-wave rectifier. The diode D is ideal. The average steady-state current (in Amperes) through the diode is approximately ____________.

The diodes and capacitors in the circuit shown are ideal. The voltage v(t) across the diode D1 is

The circuit shown in figure is best described as a

For full wave rectification, a four diode bridge rectifier is claimed to have the following advantages over a two diode circuit:

(1) less expensive transformer

(2) smaller size transformer, and

(3) suitability for higher voltage application.

Of these,
