Question 78Electricity & Electronics - 1st Asst/Chief

The correct answer is D) diode is operating properly. When a digital multimeter is used to test a silicon diode, the expected readings are: - When configured as in figure "A" (forward bias), the diode should display around 0.70 V, which is the typical forward voltage drop for a silicon diode. - When configured as in figure "B" (reverse bias), the diode should display "OL" (overload), indicating that the diode is blocking the current flow in the reverse direction, which is the proper operation of a diode. The readings provided in the question match this expected behavior, confirming that the diode is operating properly. The other answer choices (A, B, C) do not accurately reflect the diode's status based on the given multimeter readings.
