Problem 60798. Battery Life Estimation for a Device
A battery-powered device consumes a constant current while operating. The estimated battery life (T) can be calculated using the formula:
where:
- Q is the battery capacity (in ampere-hours, Ah)
- I is the device's current consumption (in amperes, A)
- T is the estimated battery life (in hours)
Write a function to estimate how long a battery will last given its capacity and the device’s current consumption.
