Which region must the positive terminal of a voltage source be connected To forward bias diode?

To forward bias a diode, the positive terminal of a voltage source must be connected to the anode of the diode. The anode is the terminal that allows current to flow into the diode when it is forward biased. The negative terminal of the voltage source should be connected to the cathode, allowing current to flow from the anode to the cathode. This arrangement enables the diode to conduct electricity.
