That resistor''s value increases as the battery capacity is drained. If it were 50 ohms and the system needed 10 mA, the terminal voltage is down by half a volt, often enough to cause the MCU to crash. Add a big capacitor, as in the following diagram, and a short pulse load can draw on the charge stored in the cap.
Figure (PageIndex{2}): (a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.

So you connect the + terminal of the DC supply to the + electrode of the battery/capacitor, and likewise for the - terminal/electrode. The DC supply drags electrons from the + electrode of the capacitor, through the DC power supply unit, to the - electrode of the capacitor. So the charge on each plate of the capacitor increases.
Capacitor Charging. When a capacitor is connected to a power source, such as a battery, it begins to accumulate or ''store'' charge. This process is known as capacitor charging. The power source provides a potential difference across the capacitor''s plates, causing current to flow. This current then accumulates as electric charge on the plates.
Since the initial voltage across the capacitor is zero, no work is initially required to move the charge. As the voltage increases, the work required increases. But the maximum work per unit charge the battery can do is its own emf, which is why charging stops when the capacitor voltage equals the emf of the battery.
If a capacitor is connected in series with a battery, then the potential difference between the plates is fixed and equal to the voltage of the battery. Therefore, if the capacitance changes, then the charge on the capacitor plates must change as well in order to keep the potential difference between the plates constant.

Also, while the battery is connected to the charged capacitor, the negative plate, connecting wire, and negative terminal of the battery are all negatively charged. Similarly for the positive plate, connecting wire, and positive terminal. Indeed, there is an electric field between the connecting wires that gives rise to the voltage across them.
You can charge a capacitor simply by wiring it up into an electric circuit. When you turn on the power, an electric charge gradually builds up on the plates. One plate gains a positive charge and the other plate gains an equal and opposite (negative) charge. ... You can see from this how a capacitor differs from a battery: while a battery makes ...
