An A.C. supply of 350 V, 60 Hz is applied to a full wave rectifier. If internal resistance of each diode is 200Omega and load resistance R_(1)=5k Omega, then the maximum value of output current is ……. |

Answer» 0.065 A `I_(m)=I_("rms")XX sqrt(2)` `=(V_("rms")xx sqrt(2))/(R_(2)+2r_(f))` where `r_(f )=` resistance of DIODE in forward bias `=(350xx1.414)/(5000+2xx200)=0.0916A` `therefore I_(m)~~0.092A` |
