Answer:
Current is calculated as the amount of charge that pass a point on a circuit per time.
Explanation:
Electric current is defined as the amount of charge that passes a point on a circuit per unit time. The mathematical definition of electric current is given by :
Where
q is a charge (Coulomb)
t is time (in seconds)
The SI unit of electric current is A. It is equivalent to C/s. So, the correct option is (A).
λ = 5.7 X 10⁻⁷m
On using quantum dot, it is 351
<u>Explanation:</u>
Given-
Frequency, f = 5.20 x 10^14 Hz
Speed of light, c = 3 X 10⁸ m/s
Wavelength, λ = ?
We know,
λ f = c
λ = c / f
λ =
λ = 5.7 X 10⁻⁷m
Dot = 2 X 10⁻⁴
So,
2 X 10⁻⁴ / 5.7 X 10⁻⁷m = 351
