3 phase explained

What are the two main components of a simple AC generator that interact to produce electricity?

• Battery and Resistor

• Capacitor and Inductor

• Rotor (Magnetic) and Stator (Copper coils)

• Transformer and Diode

What characteristic defines alternating current (AC) electricity?

• The current flows in only one direction.

• The current's direction alternates forwards and backwards.

• The voltage remains constant.

• It is primarily used in batteries.

How is the frequency of alternating current (AC) measured?

• In Volts (V)

• In Amperes (A)

• In Ohms (Ω)

• In Hertz (Hz)

What is a primary advantage of three-phase electricity over single-phase electricity for applications like powering industrial equipment?

• It uses fewer cables, making it cheaper to install.

• It provides a more constant and higher power output.

• It can only power small electrical goods.

• It eliminates the need for transformers.
