Ten million electrons pass from point P to point Q in one micro second...
Here,number of electron,
n = 10000000 = 107
Total charge on ten million electrons is
Q = ne [where e = 1.6 × 10−19C]
=107 × 1.6 × 10−19C = 1.6 × 10−12C
Time taken by ten million electrons to pass from point P to point Q is
t = 1μs = 10−6s
The current
I =
Since the direction of the current is always opposite to the direction of flow of electrons. Therefore due to flow of electrons from point P to point Q the current will flow from point Q to point P.

Ten million electrons pass from point P to point Q in one micro second...
The current is given by the equation:
I = Q/t
where I is the current, Q is the charge, and t is the time.
Since the charge is given by the number of electrons multiplied by the charge of one electron, we have:
Q = 10,000,000 * 1.6 x 10^-19 C
where C is the unit of charge.
The time is given as one microsecond, which is equal to:
t = 1 x 10^-6 s
Substituting these values into the equation for current, we get:
I = (10,000,000 * 1.6 x 10^-19 C) / (1 x 10^-6 s)
= 16 C/s
Therefore, the current is 16 Amperes. The direction of the current is not provided in the question.
