In semiconductor two charge carriers are present i.e holes and electrons.The current is rate of flow of charges.so in ptype semiconductor the current is the sum of current due to holes and electrons.But current due to holes is more compsred to electrons in ptype.
holes are the current carriers
Impure semi conductor material are called extrinsic semi conductor as there a small quantity of foreign particle is present. Two types of impurities are added to an extrinsic semi conductor. When impurities belonging to third group are called as trivalent or acceptor impurities such as boron, aluminum, indium or gallium when these impurities are added in pure semi conductors they form p-type semi conductor. And similarly when impurities belonging to group fifth called as penta valent or donor impurities such as arsenic, antimony, bismuth or phosphorus are added to a semi conductor they form N-type semi conductor .
first of all un-doped semi-conductor is said to be intrinsic semi-conductor so, there is no discussion of either N-type or P-type
Wala!
the major charge carriers are the holes.
N-type semiconductor contains extra electrons.
No, Perspex is not a semiconductor. It is a type of transparent plastic material known as polymethyl methacrylate (PMMA). Semiconductors are materials that have conductivity between that of a conductor and an insulator.
Moving a conductor through a magnetic field will produce alternatinc current (AC).
The size of a current is determined by the voltage applied, the resistance of the circuit, and Ohm's Law (current = voltage / resistance). The type of conductor material used, the temperature, and the cross-sectional area of the conductor also affect the size of a current.
The maximum amount of current a conductor can carry continuously without exceeding its temperature rating is typically determined by the conductor's ampacity rating, which is based on factors such as the conductor material, insulation type, and ambient temperature. It is important to adhere to these ampacity ratings to prevent overheating of the conductor.
GOLD IS THE VERY BEST CONDUCTOR, but for the money copper is better than aluminum and worth the extra cost.
Yes, thermocol is a good conductor of electricity.
