Q2. What is rectifier
Ans. 
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
• Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

• They are made up of diodes, which allow current to flow in only one direction.

• Rectifiers can be half-wave or full-wave, depending on the number of diodes used.

• Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli

Q3. What is scr and how it work
Ans. 
SCR stands for Selective Catalytic Reduction. It is a technology used to reduce nitrogen oxide emissions from diesel engines.
• SCR is a process that uses a catalyst to convert nitrogen oxides (NOx) into nitrogen (N2) and water (H2O).

• It involves injecting a urea-based solution, known as diesel exhaust fluid (DEF), into the exhaust stream.

• The DEF reacts with the NOx in the presence of the catalyst, breaking it down into ha...read more
