Question 159: Semiconductors and Logic Gates

Question

The reading of the ammeter for a silicon diode in the given circuit
is :

Accepted Answer

Note
:
From the circuit you can see the diode is in forward bias, and to start current flow through the circuit. Accross silicon diode the voltage drop should be 0.7  V and for Germenium diode the  voltage drop is 0.3 V.  Then diode will start working and current  will flow through the circuit.
So, the net voltage  available accros the  registor is (V
net
) = 3 $$-$$ 0.7 = 2.3 V
$$	herefore\,\,\,$$ Current flow through circuit = $${{2.3} \over {200}}$$ = 11.5 mA
