Grasim Industries Desk 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 Dc current ?
Ans. 
DC current is the flow of electric charge in a constant direction.
• DC stands for Direct Current.

• It is the type of electric current that flows in a single direction.

• DC current is produced by sources such as batteries, fuel cells, and solar cells.

• It is commonly used in electronic devices and power transmission systems.

• Unlike AC (Alternating Current), DC current does not change its direction over time.
