Q3. Mention what is the difference between generator and alternator ?
Ans. 
Generators and alternators are both electrical machines that convert mechanical energy into electrical energy, but they differ in their construction and working principles.
• Generators produce direct current (DC) while alternators produce alternating current (AC).

• Generators use a commutator and brushes to convert mechanical energy into electrical energy, while alternators use slip rings and brushes.

• Generators are typical...read more

Q2. What is the break horse power
Ans. 
Break Horse Power (BHP) is the power output of an engine measured at the output shaft without any power losses.
• BHP is the actual power delivered by an engine to do useful work

• It is measured at the output shaft of the engine

• It does not include any power losses due to friction, heat, or other factors

• BHP is often used to compare the power output of different engines

• It is calculated using the formula: BHP = (Torque x RPM)
