Resistor colour codes and FET,Transister
The voltage divider rule is used to calculate the voltage across a resistor in a series circuit.
The voltage divider rule states that the voltage across a resistor in a series circuit is proportional to its resistance.
The formula for the voltage divider rule is Vout = Vin * (R2 / (R1 + R2)), where Vout is the voltage across R2, Vin is the input voltage, R1 is the resistance before R2, and R2 is the resistance across whi...
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.
Ohm's law is expressed by the formula: V = I * R, where V is the voltage, I is the current, and R is the resistance.
The law was named after the German physicist Georg Simon Ohm, who first formulated it in 1827.
Ohm's law is fundamental in understanding and a...
FET stands for Field-Effect Transistor. It is a type of transistor that uses an electric field to control the flow of current.
FET is a three-terminal device used for amplification and switching of electronic signals.
It has a high input impedance and low output impedance.
FETs are classified into two types: JFET (Junction Field-Effect Transistor) and MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor).
The main dif...

Distillation is a process used to separate components of a liquid mixture based on differences in boiling points in a distillation column.
Distillation is a separation process where a liquid mixture is heated to create vapor and then cooled to condense the vapor back into liquid form.
The components of the mixture have different boiling points, allowing them to be separated based on their vapor pressures.
The distillation...
Haber process is a method used to produce ammonia through the reaction of nitrogen and hydrogen in the presence of an iron catalyst.
The reaction equation is N2 + 3H2 -> 2NH3
The process is carried out at high pressure (200 atm) and high temperature (450°C)
Iron catalyst is used to speed up the reaction
Ammonia is formed as a product
