Problem: The manufacturer of a 6V dry-cell flashlight battery says that the battery will deliver 15 mA for 60 continuous hours. During that time the voltage will drop from 6V to 4V.
Part A: Assume the drop in voltage is linear with time, how much energy does the battery deliver in this 60h interval?
I need help to determine how much energy the battery delivers in this 60h interval.
