Q1. What is Nodal analysis
Ans. 
Nodal analysis is a method used in electrical engineering to determine the voltage at each node in a circuit.
• Nodal analysis involves writing Kirchhoff's Current Law equations for each node in a circuit.

• It is used to analyze complex circuits with multiple nodes and voltage sources.

• The goal of nodal analysis is to determine the voltage at each node relative to a reference point, usually ground.

• It is a powerful tool for s...read more

Q1. What was the OD of 15NB, 20NB
Ans. 
OD of 15NB and 20NB is not clear without context.
• OD stands for outer diameter.

• NB stands for nominal bore.

• The OD of a pipe depends on its material, thickness, and application.

• Without context, it is impossible to determine the OD of 15NB and 20NB pipes.

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
