The formula for the power output P of a battery is P VI RI2 where V is the electromotive force in volts R is the resistance in ohms and I is the current in amperes Find the current that corresponds to a maximum value of P in a battery for which V 13 volts and R 0 5 ohm amperes Assume that a 15 ampere fuse bounds the output in the interval 0 I 15 Could the power output be increased by replacing the 15 ampere fuse with a 24 ampere fuse Yes No
