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

Q2. Explain the Transformer
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two coils of wire, known as primary and secondary coils

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy

• Used to step up or step down voltage levels in power distribution systems

• Commo...read more

Q1. Power factor What is vfd Difference between ac and dc motor
Ans. 
Power factor is the ratio of real power to apparent power in an AC circuit. VFD stands for Variable Frequency Drive. AC motors run on alternating current while DC motors run on direct current.
• Power factor is a measure of how effectively electrical power is being used in a circuit.

• It is calculated by dividing the real power (in watts) by the apparent power (in volt-amperes).

• A power factor of 1 indicates that all the pow...read more

Q2. Types of load cell
Ans. 
Types of load cells include strain gauge load cells, hydraulic load cells, and capacitive load cells.
• Strain gauge load cells measure the strain or deformation of a material.

• Hydraulic load cells use hydraulic fluid to measure force.

• Capacitive load cells measure changes in capacitance to determine force.

• Other types of load cells include piezoelectric load cells and pneumatic load cells.
