DIGICOMM Semiconductor Engineer Trainee Interview Questions and Answers

Q1. What is ohms laws? Explain
Ans. 
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's Law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It helps in calculating the current, voltage, and resistance in a circuit.

• For example, if the voltage is 12 volts and the resistance is 4 ohms, then the current flowing th...read more

Q1. What is dc and ac current and who is more power full current?
Ans. 
DC current flows in one direction while AC current changes direction periodically. Neither is more powerful, they serve different purposes.
• DC current is used in batteries and electronic devices that require a steady flow of electricity in one direction.

• AC current is used in homes and businesses to power appliances and electronics that require a changing flow of electricity.

• Neither current is more powerful, as they serv...read more
