Question 701: Current Electricity

Question

An electron revolves in a circle at the rate of $$10^{19}$$ rounds per second. The equivalent current is $$\left(e=1.6 	imes 10^{-19} \mathrm{C}ight)$$

Accepted Answer

The equivalent current produced by an electron revolving in a circle can be calculated by taking into account the charge of the electron and the rate at which it makes rounds per second.
The formula to calculate current ($$I$$) in this context is given by:
$I = n\cdot e$
where:
$$n$$ is the number of electrons passing a given point per second, and in this case, it's equivalent to the number of rounds made by a single electron per second because it's only one electron.
$$e$$ is the charge of an electron ($$1.6 	imes 10^{-19} \, 	ext{Coulombs}$$).
Given that the electron makes $$10^{19}$$ rounds per second, we have:
$n = 10^{19} \, 	ext{rounds per second}$
Therefore, to find the current, we substitute $$n$$ and $$e$$ into the formula:
$I = n\cdot e = 10^{19} \cdot 1.6 	imes 10^{-19}$
$I = 1.6 \, 	ext{A}$
So, the equivalent current is
1.6 A
. Hence, the correct answer is
Option B: 1.6 A
.
