The V-I characteristics of silicon diode is shown in Fig. Calculate the diode resistance inforward bias at V=+0.9Vreverse bias V=-3.0V.

Answer»

SOLUTION :In forward characteristic for VOLTAGE `V=+0.9V`
`DeltaV=DE=1.0-0.80=0.2V, DeltaI=CE=10-6=4mA`
`:.` Forward resistance, `R_(f)=(DeltaV)/(DeltaI)=(0.2V)/(4mA)=50OMEGA`
in reverse characteristics for voltage `V=-3V ,DeltaV=-2-(-4)=2V, DeltaI=3-2=1muA`
`:.` Reverse resistance, `R_(r)=(DeltaV)/(DeltaI)=(2V)/(1muA)=2xx10^(6)Omega`
