Answer :
To find the current, you divide the charge by the time interval. With a charge of 0.23 C and a time of 1.69 s, the current would be approximately 0.14 A.
The question asks about the current in amperes that would result when a static charge moves from a person's finger to a doorknob over a specific time interval. To calculate the current, we use the formula I = Q / t, where I is the current in amperes, Q is the charge in coulombs, and t is the time in seconds over which the charge moves.
In this scenario, the charge is given as 0.23 coulombs (C) and the time is given as 1.69 seconds (s). Plugging these values into the formula, we get
I = 0.23 C / 1.69 s
Therefore, the current is:
I = 0.1361 A
which can be rounded to I = 0.14 A (amperes).
