Lesson: Electricity Transmission Networks Physics

In this lesson, we will learn how to describe how national electricity grids work and how they respond to changes in demand.

Lesson Plan

Students will be able to

understand what causes changes in demand for electricity over the course of a day and over the course of a year,
understand that some power stations are kept below maximum operating power so that they can speed up quickly if the demand suddenly increases,
understand how quickly or slowly a power station can start up or turn off for the different main types of power stations: coal-fired, gas-fired, nuclear, and hydroelectric dam,
understand that when the electrical power is transmitted across electricity networks, it is transmitted at a high voltage and a low current.
