In the diagram,the input is across the terminals $A$ and $C$ and the output is across the terminals $B$ and $D$,then the output is

In a full-wave $P-N$ junction diode rectifier, a load resistance of $1500 \ \Omega$ is used. No filter is used. Assume each diode has a forward resistance $R_f = 10 \ \Omega$ and reverse resistance $R_r = \infty$. When a sinusoidal voltage with a peak amplitude of $30 \ V$ and frequency $50 \ Hz$ is applied, calculate the $D.C.$ power output and $A.C.$ power input respectively.

The maximum efficiency of a full wave rectifier is .........

For the given electric voltage signal,the $dc$ value is......$V$.

The electrical circuit used to get smooth $dc$ output from a rectifier circuit is called
