Yes, DC (Direct Current) will charge a capacitor. Here's how it works:
When a DC voltage is applied to a capacitor, the capacitor begins to charge. Initially, when the capacitor is uncharged, it acts like a short circuit (a path with little resistance), and current flows into the capacitor. As the capacitor charges, the voltage across its plates increases, and the current gradually decreases.
Over time, the capacitor will continue to charge until the voltage across it equals the applied DC voltage. At this point, the current flow stops because the capacitor is fully charged, and the voltage across the plates is equal to the DC source voltage.
To summarize:
So, in short, yes—DC will charge a capacitor, but only until the voltage across the capacitor equals the voltage of the DC source. After that, no more current will flow.

To summarize:
- When DC voltage is applied, current flows into the capacitor.
- The capacitor charges, and the voltage across it rises.
- Eventually, the capacitor reaches the voltage of the DC source, and the current stops flowing.
So, in short, yes—DC will charge a capacitor, but only until the voltage across the capacitor equals the voltage of the DC source. After that, no more current will flow.
