(A) In the given circuit,the $P$-terminal of the diode is connected to a potential of $1 \ V$ and the $N$-terminal is connected to a potential of $2 \ V$ through a $100 \ \Omega$ resistor.For a diode to be in forward bias,the potential at the $P$-terminal must be higher than the potential at the $N$-terminal.Here,the potential difference across the diode is $V_P - V_N = 1 \ V - 2 \ V = -1 \ V$.Since the potential at the $P$-terminal is lower than the potential at the $N$-terminal,the diode is in reverse bias.An ideal diode in reverse bias acts as an open circuit,meaning it offers infinite resistance.Therefore,no current flows through the circuit.Thus,the current through the diode is $0 \ mA$.

The current through an ideal $PN$-junction diode shown in the following circuit diagram will be ..... $mA$.
