Extracted text: B1 (ii) A typical electric-powered car having a 8 A, 14 V battery was charged at constant current from 8am till 10pm. Determine: (i) How much electric energy is used? (i) What is the cost of electricity to charge the battery? () Calculate the total energy conversion loss. (iv) What is the actual efficiency of the battery? [Data given: electric cost =$0.48/Wh, and assuming 75% battery (chemical energy) to electricity conversion, and 75% electrical to mechanical energy conversion].
