A lightning strike transfers 25.1 C of charge in (6.49x10^-3) s. The current during this lightning strike is _.__x10^ A?
Charge Q = 25.1 C
Time t = 6.49x10-3 sec
Formula for Current I = Q/t
I = 25.1 / (6.49x10-3) = 3.867 x 103 A
The current during this lightning strike is 3.867 x 103 A.
To find the current during the lightning strike, we can use the formula:
Current = Charge / Time
Given:
Charge = 25.1 C
Time = 6.49 x 10^-3 s
Substituting these values into the formula, we have:
Current = 25.1 C / (6.49 x 10^-3 s)
To simplify this calculation, we need to remember the rules of scientific notation:
a x 10^b / c x 10^d = (a / c) x 10^(b - d)
In this case, we have:
25.1 / 6.49 = 3.865
10^-3 s can be written as 1 / 10^3 = 1 x 10^-3
So, the final calculation becomes:
3.865 x 10 / 1 x 10^-3 = 3.865 x 10^3 A
Therefore, the current during this lightning strike is 3.865 x 10^3 A, or 3.865 kiloamperes (kA).
