Please try to solve step by step . Much thanks.

Given the circuit below, what is I and V as defined in the figure(note direction of V)?

Solution

In this circuit given.

The Diode will be in reverse bias, as Cathode of Diode is connected to + ve terminal of Voltage Source. While Anode of Diode is connected to -ve terminal. Diode acts as open circuit.SO the entire Supply Voltage will Appear across the Diode.

I,e -12v will be shown

Moreover the current will be Zero since the circuit is open circuit.
