How do you test a voltage regulator using ohmmeter?

To test a voltage regulator using an ohmmeter, first disconnect the regulator from the circuit to ensure accurate readings. Then, measure the resistance between the input and output terminals; a good regulator should show a high resistance (often infinite). Next, check the resistance between the ground terminal and the output terminal; a low resistance reading typically indicates a short circuit, while a high reading suggests the regulator is functioning properly. Finally, compare your readings with the manufacturer’s specifications for definitive results.
