T1/2 means that the voltage (or charge) of the system will increase to half more of what is left in a time equal to t1/2 seconds. Therefore if a system is already at half charge (t1/2 seconds after starting) then after t1/2 more seconds the system will be charged to 50% plus half of 50%. That is 25% more, or 75% of the entire charge. Let's say that four t1/2's have gone by. That means that the charge (or voltage) is at (50% + 1/2*50% + 1/2*1/2*50% + 1/2*1/2*1/2*50%) = 93.75% of maximum charge. Yikes! Now look in your manual for a more simple mathematical derivation of this concept.

  Fraction =∑ / 2ⁿ       n = 0, 1, 2, 3 ...

Explanation:

Let's write this expression

     Fraction = 50 + ½ 50 + ½ ½ 50 + ½ ½ ½ 50

Let's call the number as a

    Fraction = a / 2⁰+ a / 2¹ + a / 2² + a / 2³

We can see that exponent is    n = 0, 1, 2 ...

It can be written in summary form

    Fraction = ∑ a / 2ⁿ

   n = 0, 1, 2, 3

    Fraction =∑ / 2ⁿ       n = 0, 1, 2, 3 ...

Where n is the number of cycles of

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
