1. Draw a schematic diagram of Daniell's cell. Write cell line notation and calculate standard cell potential. 2. Can an electrode act as both anode and cathode? Explain the situation. 3. What is the role of platinum wire? Why can't we use a cheap and readily available copper wire? 4. A car battery is generally 12V. It is theoretically possible to combine them in series circuit to make 220V. Why this method is not used in a car or bus that has an electrical socket for home appliance
