Question
Mr. Physics' cell phone battery has a charge capacity of 5, 040 mAh and is currently at 30%. He wants it to reach 100% before
Mr. Physics' cell phone battery has a charge capacity of 5, 040 mAh and is currently at 30%. He wants it to reach 100% before he can take it with him. (a) Convert Mr. Physics' cell phone battery charge capacity from mAh to C. [2] 1 mAh = 3.6 C Mr. Physics' phone charger is rated at an output of 33W and 11 V. (b) Determine the output current of Mr. Physics' phone charger. (c) Hence, determine, in minutes, how long it would take to charge Mr. Physics' phone to 100%. (d) If Mr. Physics charges his phone like this every day for a 30-day month, determine how many hours it is charged for in that 30-dav month. (e) Hence, calculate how much energy, in kWh, is used to charge Mr. Physics' phone in a 30-day month. (f) Given that the energy rate is S0.33 per kWh, determine the cost to charge Mr. Physics' phone.
