N.C.L. Industries Electrical Engineer Interview Questions and Answers

Q1. What is Ohm's Law?
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• For example, if a circuit has ...read more

Q1. What is the process of power distribution?
Ans. 
Power distribution is the process of delivering electricity from power plants to consumers through a network of transmission and distribution lines.
• Electricity is generated at power plants using various sources such as coal, natural gas, nuclear, or renewable energy.

• The electricity is then transmitted at high voltages over long distances through transmission lines to substations.

• At substations, the voltage is reduced a...read more
