Which of these is a renewable energy source?

• Coal

• Solar energy

• Natural gas

• Nuclear energy

What do we call the wires that carry electricity over long distances?

• Distribution cables

• Transmission lines

• Circuit wires

• Power lines

What is the purpose of a transformer in power systems?

• To change voltage levels in power systems.

• To increase current levels in power systems.

• To store electrical energy for later use.

• To convert AC to DC power.

Which component helps to distribute electricity to homes?

• Power generator

• Voltage regulator

• Distribution transformer

• Circuit breaker

What is the main function of a power plant?

• To provide heating for residential areas.

• To purify water for drinking purposes.

• The main function of a power plant is to generate electricity.

• To store energy for later use.

What type of energy does a wind turbine generate?

• Thermal energy
