Final answer:
The current when a typical static charge of 0.250 μC moves from your finger to a metal doorknob in 1.00 μs is 0.25 A.
Step-by-step explanation:
The current when a typical static charge of 0.250 μC moves from your finger to a metal doorknob in 1.00 μs can be calculated using the formula:
Current = Charge / Time
Substituting the given values, we have:
Current = 0.250 μC / 1.00 μs = 0.25 A
So, the correct option is b) 0.25 A.
