Find the current when 2.00 nC jumps between your comb and hair over a 0.500-μs time interval.

a) 4.00 A
b) 0.50 A
c) 8.00 A
d) 1.00 A

Answer :

Final answer:

To find the current, use the formula I = Q/t, where I is the current, Q is the charge, and t is the time interval. Substitute the values given and calculate the current. The correct answer is 4.00A.

Explanation:

To find the current, we need to use the formula for electric current:

I = Q/t

where I is the current, Q is the charge, and t is the time interval. In this case, the charge is 2.00 nC (nanocoulombs) and the time interval is 0.500 μs (microseconds). Convert the charge to coulombs and the time interval to seconds:

2.00 nC = 2.00 x 10^-9 C

0.500 μs = 0.500 x 10^-6 s

Now, substitute these values into the formula:

I = (2.00 x 10^-9 C)/(0.500 x 10^-6 s) = 4.00 A

Therefore, the current is 4.00 A, so the correct answer is option a) 4.00 A.
