In a diode, current flows from the _____ to the _____.

In a diode, current flows from the anode to the cathode. This is based on the fundamental operation of a diode, which is a semiconductor device that allows current to flow primarily in one direction. When a forward voltage is applied (meaning the anode is at a higher potential than the cathode), the diode becomes conductive, allowing current to flow through it from the anode (the positive side) to the cathode (the negative side).

Therefore, the correct understanding of current flow aligns with the direction of electron movement, which is from regions of negative charge (the cathode) to regions of positive charge (the anode). However, conventional current flow, which is the flow of positive charge, is considered to move from the anode to the cathode. This distinction is crucial in understanding how diodes function within electronic circuits.
