You decide to use a battery labeled “205 mAh 1S” with a total voltage of 3.7 V. What is the overall energy capacity of the batte
harkovskaia [24]

Answer: 0.7585Wh

Explanation:

Battery capacity = 205 mAH

Nominal Voltage (V) = 3.7

The overall energy capacity of the battery is measured in watt-hour. Which is the product of the battery capacity in Ampere-hour(AH) and the nominal voltage of the battery in volt (V)

205mAH = 205/1000 = 0.205AH

Therefore, energy capacity:

0.205AH × 3.7 V = 0.7585Wh

This gives us the amount of energy stored in the battery per hour.

Therefore, a battery with nominal voltage of 3.7V and current capacity of 205mAH has a maximum energy capacity of 0.8585Wh.

How does abstraction help us write programs
Misha Larkins [42]

Answer:

Abstraction refines concepts to their core values, stripping away ideas to the fundamentals of the abstract idea. It leaves the common details of an idea. Abstractions make it easier to understand code because it concentrates on core features/actions and not on the small details.

This is only to be used for studying purposes.

Hope it helps!
