Forward bias Diode in AC

Voltage after applied V = 4.3v

V = 5*1 = 5V

I = 4.3/1000 = 0.0043Ma

-         Vₒ = 0V

IR = Iₒ = 5V/1000 = 5mA

-         Vₒ = 0.7V

IR = Iₒ = 5v-0.7/1000 = 4.3Ma

-         Vₒ = 0.7v     Rₒ = 4ꭥ

IR = Iₒ = 5V-0.7V/1000+4 = 4.2Ma

Iₒ = 4.5mA

Vₒ = 0.725v

          Reverse bias Diode in AC

Iₒ = 0mA

VR = 0V

Vₒ = 5V
