Calculate the energy transferred by a 12V hairdryer, running on a current of 0.50A, that is left on for 8.0 minutes.

Energy = 0.8 W•hr

Explanation:

Energy delivered is 12 V(0.50)A(8.0/60)hr = 0.8 W•hr

This is often confused with the power consumption which is calculated using the same numbers, but in a different way for a different purpose

The power consumption rate is 12V(0.50 A) = 6 W or 6 J/s

working for 8 minutes means a total power consumption of

6 J/s(8 min(60 s/min)) = 2880 J

Energy is what the power company bills you for

It is usually sold in units of kW•hrs.

when it gains or loses electrons

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
