The document provides information about a classroom lesson on electricity. It includes class rules, questions about different power plants in the Philippines, objectives to describe how electricity moves from generation to homes, and instructions for a group activity to trace the path of power. It discusses producing electricity in power plants, transmitting it through high-voltage lines, distributing it through substations, and finally delivering it to homes and businesses. The document aims to teach students how electricity is generated, transmitted, and distributed from the source to consumers.

1. GOOD
AFTERNOON
STUDENTS!

2. CLASS RULES:
1.Raise your hand if you want to
answer.
2.Ask permission from the teacher
if you want to go out.
3.When I say “Class” you answer
“Yes”.
4.When I say “Hands and Eyes” you
claps your hands together.
5.When I say “Mirror Me” you need
to follow what I do or say.

4. QUESTIONS:
Can you enumerate the
different power plants
in the Philippines that
supply electricity in
our homes?

5. Hydroelectric power plant in Iligan City

6. Calaca Coal-Fired Plant in Calaca Batangas

17. What are the different
stations in the
transmission of energy?
Electricity is produced in the power plants,
transmitted at high current and voltage in
transmission substations, passed through the
distribution substations, then finally distributed
to business and residential areas.

18. What do you notice
about the size of the
transmission lines as it
reaches the consumers?
Transmission lines have a greater cross-
sectional area to allow a large amount of
current to pass through and residential
wirings have much smaller cross-sectional
area.

19. Does the size of wire and
cables used matter in energy
transmission?
Yes, it ensures safety in the entire
network system and reduces
transmission losses.

20. What happens to the
voltage that travels from
the source to the
consumers?
The voltage is stepped-up for
transmission and stepped-down
before being distributed to
households.

21. “INDIVIDUAL ACTIVITY”

22. How to use
electricity wisely?
Switch off your all appliances
and lights when not in use.

23. How electricity is
transmitted and distributed
from the generating power
plants to the different
places in the community?

24. From the power plants, electricity is then made
to travel along cables and wires called
transmission lines. Transmission lines are
commonly put up between transmission
substations which are regulated by the National
Power Corporation. They are operated at high
voltages, end out large amounts of electrical
power and extend over considerable distances.
The distribution system connects the
transmission system to the customer’s
household.

25. Can you identify the
different stages of
power generation,
transmission and
distribution?

26. From the generating station, the
transmission substations step up the
voltage to a range of 765,000 volts.
Within the operating area,
transmission substations reduce (step
down) the transmitted voltage to
34,500 – 138,000 volts. This power is
then carried through lines to the
distribution systems located in the
local service area.
