SSP India Interview Questions, Process, and Tips

Power is the rate at which work is done or energy is transferred in an electrical system.

• Power is measured in watts (W) and calculated using the formula P = V x I, where P is power, V is voltage, and I is current.

• In single phase systems, power can be calculated using P = V x I, where V is the line voltage and I is the current.

• In 3 phase systems, power can be calculated using P = √3 x V x I, where V is the line voltage ...read more

PLC stands for Programmable Logic Controller, used in automation to control machinery. VFD is Variable Frequency Drive, used to control motor speed.

• PLC is a digital computer used for automation of electromechanical processes.

• PLC can be programmed to perform a variety of tasks such as controlling machinery, processes, and more.

• VFD is a type of motor controller that drives an electric motor by varying the frequency and v...read more

Voltage is the electrical potential difference between two points, measured in volts. Current is the flow of electric charge, measured in amperes.

• Voltage is the electrical potential difference between two points, measured in volts. It is typically measured using a voltmeter.

• Current is the flow of electric charge, measured in amperes. It is typically measured using an ammeter.

• The size of a cable is determined by its cur...read more

Sanity testing is a narrow and focused testing to ensure core functionality works, while smoke testing is a broader testing to check if the software is stable enough for further testing.

• Sanity testing is a subset of regression testing, focusing on specific areas of functionality.

• Smoke testing is a preliminary testing to check if the software build is stable enough for further testing.

• Sanity testing is usually performed...read more
