Question

What current is flowing in a wire if 0.47 C of charge pass a point in the wire in 0.20 s?

A. 0.47 A
B. 0.20 A
C. 2.4 A
D. 0.094 A

Answer 1

To find the current in the wire, the charge (0.47 C) is divided by the time (0.20 s), resulting in a current of 2.35 A.

Step-by-step explanation:

The current flowing in a wire can be calculated by dividing the charge that passes a point in the wire by the time it takes for this charge to move past the point. As per the given question, 0.47 Coulombs of charge pass a point in 0.20 seconds. Using the formula I = Q / t, where I is the current, Q is the charge in Coulombs, and t is the time in seconds, we get:

I = 0.47 C / 0.20 s = 2.35 A. Therefore, the correct answer is C. 2.4 A (rounded to one decimal place).
