Question

What is the current when a typical static charge of 0.250μC moves from your finger to a metal doorknob in 1.00μs?

a) 250 A
b) 0.25 A
c) 2.50 A
d) 0.0025 A

Answer 1

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.
