### Step-by-Step Solution #### Part (a): Charge Transfer in a Parallel Plate Capacitor 1. **Understanding the Capacitor Connection**: - When a parallel plate capacitor of capacitance \( C \) is connected to a battery with an electromotive force (emf) \( E \), the battery starts transferring charge to the capacitor. - The plate connected to the positive terminal of the battery loses electrons, becoming positively charged, while the plate connected to the negative terminal gains electrons, becoming negatively charged. ...
