A p-n junction in series with a resistance of 5 kOmega is connected across a 50 V DC source . If the forward bias resistance of the junction is 50 Omega , the forward bias current is

A p-n junction diode has a forward bias resistance of 10 Omega and a reverse bias resistance of 10 k Omega . It is connected in series with a resistance of 990 Omega and a.d.c. source of 5V in such a way that the negative terminal of the source is connected to then region of the p-n junction. What is the current flowing in the circuit?

An ideal p-n junction diode can withstand currents up to 10mA under forward bias. The diode has a potential difference of 0.5V across it which is assumed to be independent of current .What is the maximum voltage of the battery used to forward bias the diode when resistance of 200 Omega is connected in series with it.
