In a half-wave rectifier using a $PN$ junction diode,the input voltage has an amplitude of $25 \ V$ and a frequency of $50 \ Hz$. No filter is used,and the load resistance is $1000 \ \Omega$. The forward resistance of the diode is $10 \ \Omega$. The $d.c.$ power output and $a.c.$ power input are respectively:
- A$55 \ mW, 155 \ mW$
- B$62 \ mW, 155 \ mW$
- C$75 \ mW, 205 \ mW$
- D$70 \ mW, 170 \ mW$
