Q1. What is capacity your furnace
Ans. 
The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.
• Furnace capacity is determined by the amount of heat it can produce.

• It is usually measured in BTUs (British Thermal Units) or tons.

• Higher capacity furnaces can produce more heat and are suitable for larger spaces.

• For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000

Q3. What is working pricniple of induction motor?
Ans. 
An induction motor works on the principle of electromagnetic induction to generate rotating magnetic fields.
• Induction motor has a stator with a set of windings that are connected to an AC power source.

• When AC current flows through the stator windings, it creates a rotating magnetic field.

• This rotating magnetic field induces current in the rotor windings, causing the rotor to rotate.

• The speed of the rotor rotation is sl...read more

Q3. What is the altenator
Ans. 
An alternator is a device that converts mechanical energy into electrical energy in the form of alternating current.
• An alternator is commonly used in vehicles to charge the battery and power the electrical system.

• It consists of a rotor, stator, diode rectifier, and voltage regulator.

• Alternators produce alternating current (AC) which is then converted to direct current (DC) for use in the vehicle.

• They are more efficient...read more
