Answer to Question #206388 in C for Elaine

Question

We want to design a program to manage battery models.

(a) Define a function Recharge that sets a battery of type BatteryModel representing the present energy reserve to its maximum capacity.

The following formula are to be used in your design:

p = vi p is the power in watts (W)

v is the voltage in volts (V)

w = pt i is the current in amps (A)

w is the energy in joules (J)

t is the time in seconds (s)

(b) Create a main function that tests your functions by creating a 12-V automobile battery object of type BatteryModel, that has a maximum energy storage of 5×106

J. Use the battery to power a 4-A light for 15 minutes. Then find out how long the battery’s remaining energy could power an 8-A device. Then find out how long the battery’s remaining energy could power an 8-A device. After recharging the battery, ask again how long it could operate an 8-A device.
