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 is the majority carrier in an n type semiconductor?
p-type majority carriers are holes n-type majority carriers are electrons
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.
A very severe genetic sickness occurs in about 1 in every 100000 individuals Calculate the frequency of carriers for this recessive disease?
I'll get it started, but this is a complicated question. Assuming this is an autosomal trait, and assuming it only has one gene, and assuming it causes death before reproductive age: In order for someone to develop the phenotype, both parents have to be carriers. So, for the 1 out of 100,000 child born with the disease, you had to have 2 carriers mate. But there were more than 2 carriers in the 100,000. How many carriers do you have to have for 2 of them to mate? For that, you'd have to know how many people out of a population of 100,000 actually mate in the first place. You'd also have to know the average number of children resulting from a union. Let's say 75% of people mate, and the average number of children is 2. So of 100 people, 75 mate. But each union involves 2 people, so there are actually 37.5 pairings, producing 37.5 x 2 = 75 children. Now, assuming a frequency of carriers of F, what is the likelihood of 2 carriers mating? Let's say that everybody mates. So out of 100 people, there are 50 pairings. So the probability of mating with a carrier is approximately F.
What is the impacts to society of the aircraft carriers?
Aircraft can strike any city anywhere anytime, thanks to the aircraft carrier. Stated another way: Prior to the carrier, airplanes NEEDED a land base to operate from. So if a country or city was too far away from any land, it would be virtually safe from air attack because NO AIRPLANE could reach it. Thanks to the carrier; no land (island) is needed.
How can one determine the drift velocity of charged particles in a conductor?
To determine the drift velocity of charged particles in a conductor, one can use the formula: drift velocity current / (number density of charge carriers cross-sectional area charge of each carrier). This formula takes into account the current flowing through the conductor, the density of charge carriers, the cross-sectional area of the conductor, and the charge of each carrier. By plugging in these values, one can calculate the drift velocity of the charged particles.
What is the equation for mean drift velocity?
The equation for mean drift velocity (Vd) is given by Vd = I / (n * A * q), where I is the current flowing through the conductor, n is the number density of charge carriers, A is the cross-sectional area of the conductor, and q is the elementary charge of the charge carrier.
Why the magnitude of drift velocity is so small?
The magnitude of drift velocity is small because it represents the average velocity of charge carriers in a material experiencing an electric field. The individual charge carriers move at high speeds, but they collide frequently with atoms in the material, leading to a net low average velocity. The drift velocity is proportional to the strength of the electric field and inversely proportional to the charge carrier's mobility and the charge density.
What relation between electric current and drift velocity?
The drift velocity of free electrons in a conductor is directly proportional to the magnitude of the electric current flowing through the conductor. This means that as the current increases, the drift velocity of the electrons also increases. The relationship is described by the equation I = nAvq, where I is the current, n is the number density of charge carriers, A is the cross-sectional area of the conductor, v is the drift velocity, and q is the charge of the charge carrier.
What is the differenc e between drift diffusion current?
Specifically, drift relates the movement of a carrier (e.g., an electron or hole) to an applied electric field (i.e., the velocity of the carrier is proportional to the electric field, where the proportionality constant, mobility, is a quantity derived in solid-state physics). Diffusion relates the movement of carriers due to random (i.e., thermal) behavior and non-uniform distribution (i.e., the velocity of the carrier is proportional to the logarithmic derivative of the density of carriers, where the proportionality constant, the diffusion constant, is a quantity derived in solid-state physics).
Can you call your mail woman mail carrier?
Female mail carriers are called "letter carriers", or "mail lady", or "mail carrier". If she is nice looking and you're feeling daring, call her "mail babe"....just kidding. All letter carriers like to be called by their name, so get to know your carrier and call him/her by name.
How many cars can fit on a car carrier?
On an average a car carrier semi trailer can carry 8 to 10 small cars or 6 to 8 big cars. But there are different types of car carriers available in the market like 3 car carriers, 4 car carriers, 5 car carriers and so on. You can contact TopStart Trailers to find out these trailers with a great deal.
What is the name for a electron carrier?
A conductor (of electricity)Electric conductor
What are the names of some auto carriers?
Some of the largest auto carriers, also known as car carriers, are United Road Services, FS Auto Carriers and OK Auto Carrier. Reviews of auto carrier companies can be found on the Transport Reviews website.
What actors and actresses appeared in The Burden Carriers - 2007?
The cast of The Burden Carriers - 2007 includes: Todd Anderson as Burden Carrier John Flax as Burden Carrier Rod Harrison as Burden Carrier Mona Malec as Burden Carrier Vanessa Rios Valles as Burden Carrier
What attack did US make on Japanese carriers?
I can think of five battles/actions that resulted in loss/damage to the Japanese carriers: 1) Doolittle raid damaged on carrier 2) Coral Sea battle sank a light carrier/damaged a bigger carrier 3) Midway battle sank four carriers 4) US sub sank Japan's super carrier 5) Battle Leyete Gulf sank several carriers.

Fleet Aircraft Carriers. (Fleet Carriers are a navy's largest carrier).
