A red lead on a multimeter typically indicates the positive terminal for measuring voltage, current, or resistance. It is used in conjunction with the black lead, which is the negative or common terminal. When measuring, the red lead should be connected to the positive side of the circuit or component being tested. Always ensure the multimeter is set to the appropriate mode for the measurement being taken.
