The storage capacitor of the DEL stores which type of electrical charge?

The storage capacitor of the DEL stores which type of electrical charge?

• A. Positive Charge
• B. Negative Charge
• C. Photons
• D. Electrons

Answer: (A)

A storage capacitor holds energy by separating charge on its two plates. When the DEL cell stores a value, the storage plate is charged to a higher potential, so it accumulates a positive charge relative to the reference, while the opposite plate carries an equal negative charge. The information stored is tied to that positive charge on the storage node, making positive charge the correct description. Photons aren’t involved, and while electrons contribute to the charge distribution, the meaningful description is the positive charge stored on the storage plate.
