Fundamentals of Electrical Engineering Quiz

What is the main difference between direct current (DC) and alternating current (AC)?

• DC and AC both flow in one direction

• DC flows in one direction, while AC changes direction at specific intervals

• DC changes direction at specific intervals, while AC flows in one direction

• DC and AC both change direction at specific intervals

In which type of circuit does the voltage and current always flow in one direction?

• Alternating current (AC) circuit

• Direct current (DC) circuit

• Both DC and AC circuits

• Neither DC nor AC circuits

What is the role of electrons in an electrical circuit?

• They have no role in the circuit

• They create resistance in the circuit

• They generate the voltage supply in the circuit

• They carry the electrical energy from the generator to the consuming device

What is the primary reason for the introduction of automated systems in production?

• To produce goods less expensively than the competition

• To reduce the quality of the produced products

• To increase the complexity of the production process

• To eliminate the need for skilled workers

What is the impact of automation technology on employment?

• No impact on employment

• Increase in the number of available jobs

• Decrease in the responsibility of individual employees

• Loss of jobs, especially those with a low skill level
