What are the differences between nmos and pmos transistors?
NMOS is built with n-type source and drain and a p-type substrate, while PMOS is built with p-type source and drain and a n-type substrate. In a NMOS, carriers are electrons, while in a PMOS, carriers are holes. When a high voltage is applied to the gate, NMOS will conduct, while PMOS will not. Furthermore, when a low voltage is applied in the gate, NMOS will not conduct and PMOS will conduct. NMOS are considered to be faster than PMOS, since the carriers in NMOS, which are electrons, travel twice as fast as holes, which are the carriers in PMOS. But PMOS devices are more immune to noise than NMOS devices. Furthermore, NMOS ICs would be smaller than PMOS ICs (that give the same functionality), since the NMOS can provide one-half of the impedance provided by a PMOS (which has the same geometry and operating conditions).
Why the resistance of PMOS is greater than NMOS?
because pmos has low mobility . the inverter threshold voltage can be shifted to the middle and the inverter is more symmetrical in terms of transistor times.
Why P-type semiconductors mosfet are not use generally?
in case p type semiconductor mosfet the carriers are holes whose mobility is much less then electrons hence they are not used. when mosfets were introduced originally PMOS was much more common than NMOS, because process for PMOS devices was simpler. but as process methods improved things transitioned to NMOS due to higher speed of operation due to greater carrier mobility (as explained above) and eventually CMOS due to lower power consumption. The same was true for similar reasons with bjts: PNP was easier to make but NPN was faster.
What are the advantages of PMOS and NMOS?
* reduce the complexity of the circuit* low static power consumption* high noise immunity* high density of logic function on a chipThe most important advantage of CMOS is the very low static power consumption in compare with NMOS technology. On the other hand, CMOS technology is more complex to fabricate then NMOS technology, so it is more expensive. However, almost every todays digital circuits are CMOS. You want to use NMOS only when you want to fabricate fast and low-cost a simple circuit. The most important advantage of CMOS is the very low static power consumption in compare with NMOS technology.

Which do you think contains more matter and occupies more space 1kg of iron or 1kg of cotton?
iron
Which book in the Old Testament occupies more space in the Bible than any other book?
dueteronomy
Which of the following occupies more space a ball with with a radius of 4cm it a cube with an edge of 60mm?
The ball has more volume than the cube
What size for a picture is '1mb'?
Usually pictures of JPEG or BMP occupy more space than the GIF which occupies the low space. In JPEG and BMP there is space for the background also.
How do you explain when a state of matter is said to have definite volume?
A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.A liquid or solid will not take up a larger space than the space it occupies; even if more space is freely available.On the other hand, both a liquid and a solid are incompressible, for most practical purposes; that is, you can't compress it to use less space than the space it uses, either.
1 gallon of milk has more volume then 1 gallon of or orange juice?
(Is that a question? That is a statement.) A gallon is a measure of volume, of how much space the fluid occupies. 1 gallon of milk has the same volume as 1 gallon of orange juice. They occupies the same amount of space. Different fluids have different densities. Density is how much mass occupies a given volume. If the density of one fluid is greater, it has more mass, and it weighs more. A gallon is a gallon.
Does the amount of matter you have change the density of the matter?
The density will change if the amount of matter in the same volume changes. You can have more matter wihtout changing the density, if the matter occupies more space.
How does density change with different objects?
The density changes with different objects as all have different mass and volume(the space an object occupies) and the more compressed(Compact) the object is the more density it has.
