We will solve this problem using the direct concept related to band gap energy, that is, a band gap is the distance between the valence band of electrons and the conduction band, i. e, the energy range in a solid where no electron states (Electronic state) can exist Mathematically can be described as,
Where,
h = Planck's constant
n = Energy level
mc = Effective mass of the point charge
R = Size of the particle
As you can see the energy is inversely proportional to the size of the particle:
Therefore if the size is decreased, the amount of energy is increased.
Answer : The average value of current is .
Explanation :
It is given that,
Net charge, q = 5 C
Time, t = 0.05 s
The electric current is defined as the rate of change of electric charge.
or
The average current is .
Hence, this is the required solution.
