I am assuming the charge carries are electron and hole in an semiconductor.
the mobility of charge carriers can be understood as the easy with which the carrier can move in a semiconductor.
the mobility depends on many factors like the semiconductor material (because of the crystal structure), semiconductor specimen temperature, the effective mass of carrier, the applied electric field across the specimen.
in general if we compare the mobility of electron with hole in a silicon semiconductor, the mobility values at room temperature is some thing around 1350 cm^2 per volt sec and 450 cm^2 per volt sec for electron and holes. that is mobility of electron is 2-3 time more than the holes in silicon.

Why charge carriers are not present in depletion region of am pn junction?
depletion region is formed only after recombination of holes and electrons..so in depletion region there are only and only immoble positive and nagative ions...hence,there is no charge carrier..
When the light decreases the reverse minority-carrier current in a photodiode?
When light decreases, the generation of electron-hole pairs in a photodiode diminishes, leading to a reduction in the minority-carrier concentration. This results in a decrease in the reverse minority-carrier current, as there are fewer charge carriers available to contribute to the current flow. Consequently, the photodiode's response weakens, indicating less sensitivity to light. In essence, decreased light leads to lower photocurrent due to reduced carrier generation.
Will a charge exit a circuit with less energy than they had when they entered the circuit?
It makes sense for charge carriers to lose energy in a circuit, but I don't think it quite works that way. For example, a voltage doesn't accelerate an electron or other charge carrier at a single point - rather, the force experienced by the charge carriers would be spread out over a larger area.
How does the current flowing in a conductor depend on the number of mobile charge carriers per unit length on their average velocity on the charge per carrier?
the flowing in the conductor is related as given by the relation... I=Vena v=drift velocity of electron e=charge on electron n=concentration of electron in the current carrying conductor . a=area
Why p type semiconductor has majority charge carrier as hole?
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.

What If FRC in shipping?
If FRC (Free Carrier) is used in shipping, the seller is responsible for delivering the goods to the carrier nominated by the buyer at the seller's location. The risk transfers from the seller to the buyer once the goods are handed over to the carrier. It is important to clearly define the delivery point and carrier in the sales contract to avoid any confusion or disputes during the shipping process.

To define current why do you use the term net charge crossing a plane?
We use the term net charge to define current due to unbalanced charges that flow.
Why value of hall coefficient is negative?
The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
Define negative charge without using mass of electron?
Mass and charge are not connected. Negative charge is the charge carried by an electron.
What is the fundamental carrier of electric charge?
The fundamental carrier of electric charge is the electron. The charge on one electron is 1.6021765 × 10−19 Coulomb, and is negative. Charge can't exist in any smaller quantity, and all charges are multiples of this quantity. Protons have a positive charge of the same quantity, but they stay in their respective nuclei and don't participate in the movement of charge from place to place.
