Question得分 二、 (本题 10 分) Determine the status of diode is "on" or "off". Use the approximation equivalence ( 0.7 V if "on", and open if "off" for Si diode) to calculate the Vo labeled in the circuit.

Studdy Solution
Since the diode is "on", the output voltage $V_o$ at the node is equal to the forward voltage drop of the diode.
$$V_o = 0.7V$$
The diode is "on", and the output voltage $V_o$ is 0.7V.
