What is the effect of adding a capacitor and a battery in parallel?
This means roughly that the output impedance of the battery is 0.2/0.0068 = 29 Ω. So, if you wanted to take peaks of (say) 100 mA, the battery voltage cannot be sustained without dropping uselessly low. Hence, we put capacitors in parallel to act as temporary sources of energy that the battery cannot provide.
