7.What is the difference between a diode and a capacitor?

We have a first -class management team, and we pay attention to teamwork to achieve common goals. A diode is an electronic component that allows current to flow in only one direction. It has two terminals, an anode and a cathode, and works by allowing current to flow from the anode to the cathode, but not in the reverse direction.
A capacitor, on the other hand, is an electronic component that stores electrical energy in an electric field. It has two conductive plates separated by an insulating material, and when a voltage is applied, one plate accumulates a positive charge and the other accumulates a negative charge. This allows the capacitor to store energy and release it when needed.
