Bajaj Electricals Manual Testing Interview Questions and Answers for Experienced

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 named after Georg Simon Ohm, a German physicist.

• It is commonly used in electrical engineering and physics.

• The formula for Ohm's law is I = V/R, where I is the current, V is the voltage, and R is the resistance.

• Ohm's law can be used to calculate the current, voltage, or resi...read more

AC stands for alternating current and DC stands for direct current.

• AC changes direction periodically while DC flows in one direction.

• AC is used for power transmission while DC is used for electronic devices.

• AC voltage can be easily changed using a transformer while DC voltage cannot be changed easily.

• AC is more dangerous than DC as it can cause muscle contractions and fibrillation.

• Examples of AC sources are generators ...read more

Electricity can be generated through various methods such as thermal, hydro, nuclear, and renewable sources.

• Thermal power plants use coal, oil, or gas to heat water and produce steam that drives turbines to generate electricity.

• Hydroelectric power plants use the force of falling water to turn turbines and generate electricity.

• Nuclear power plants use nuclear reactions to heat water and produce steam that drives turbine...read more
