Tenneco Interview Questions, Process, and Tips

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). Three-phase connection refers to a system that uses three conductors to carry three alternating currents that are out of phase with each other.

• Rectifiers are commonly used in power supplies and electronic devices to convert AC to DC.

• Three-phase connections are used in industrial and commercial settings to power large moto...read more

AC and DC supplies differ in their voltage polarity and frequency.

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

• AC voltage has a frequency typically of 50 or 60 Hz while DC voltage has a constant voltage level.

• AC voltage is used for power transmission over long distances while DC voltage is used for electronic devices.

• AC voltage can be easily stepped up or down using transformer...read more

TRANSFRAMER is not a known term. DC GENERATOR is a device that converts mechanical energy into electrical energy.

• TRANSFRAMER is not a known term in electrical engineering

• DC GENERATOR is a device that converts mechanical energy into electrical energy

• DC generators are commonly used in power plants and electric vehicles

The exhaust working principle involves removing and expelling waste gases from an engine or industrial process.

• Exhaust systems are designed to collect and direct waste gases away from the source.

• In internal combustion engines, the exhaust system includes components such as the exhaust manifold, catalytic converter, and muffler.

• The exhaust gases are expelled through the tailpipe, reducing noise and emissions.

• Exhaust sys...read more
