Question

A beam of protons is moving toward a target in a particle accelerator. This beam constitutes a current whose value is 0.46A. (a) How many protons strike the target in 21 seconds?

Answer 1

By definition of current,
\[ I = \frac{charge}{time} \]
a current means every second 0.46 Coloumb of charge goes by.

Can you answer the question now?

Answer 2

*a current **of 0.46 Amperes** means every second 0.46 Coloumb of charge goes by
