Title: Recap: Transmission and Distribution

Q: HVDC is the dominant technology used for transmission lines.
A: false

Q: The law of ohmic heating is known as
- Joule's law (correct)
- Faraday's law
- Eddison's law
- Tesla's law

Q: The law of ohmic heating states that
- power losses in a conductor are proportional to the product of the squared current and the conductor resistance. (correct)
- power losses in a conductor are equal to the product of the squared current and the conductor resistance.
- power losses in a conductor are proportional to the product of the current and the squared conductor resistance.

Q: In transmission lines, [...] losses are a technical key aspect relevant for their operation. A [...] current is associated with lower power losses. When the voltage is stepped-up, the current is [...] accordingly. [...] perform such operation which can, depending on their type (and its design features), mean that the voltage is stepped-up or stepped-down.
A: power; lower/smaller; decreased/lowered/stepped-down; Transformers

Drag the words into the correct boxes

Q: The [...] frequency in Europe is [...] Hz. In other parts of the world also [...] Hz is commonly used. Automatic [...] Control is used in order to maintain the [...] close to its [...] value. Historically, the [...] side compensated for frequency fluctuations. However, [...] enable for the implementation of [...] through which one may leverage the flexibility potential on the load side.
