3. 1. Where does electricity start from?
From the video, how is it
generated/produced?
2. Where does the electricity travel?
What happens as it reaches one
station to another?
3. What is the last receiver of the
electricity? How does it reach there?
4. Problem Solving
1. What is the current basic circuit that
uses a 60-V battery and has four 20
Ω resistors?
2. What is the voltage of a basic circuit
that has a pair of 30 Ω resistors and
has an electric circuit of 5A?
5. Problem Solving
1. What is the current basic circuit that
uses a 60-V battery and has four 20
Ω resistors?
2. What is the voltage of a basic circuit
that has a pair of 30 Ω resistors and
has an electric circuit of 5A?
6. E = Pt
Energy used = (Power)(time)
Cost = Energy used x Charge per kWh
7. 1. At home, Jessie and his siblings use 3
computers for their online class for 4 hours
every day and together use 8.3 kW. How much
energy is used in a day?
2. Anna watches TV on Saturday after her
modular class on weekdays. If the TV has 400
watts and she used it for 8 hours, how much
does it cost if electricity is ₱6.88 per kWh?
Conversion 1 kW = 1000 W
8. Last February, Mrs. Terry’s electric
meter reads 8765 kWh. How much will
she pay for the power generation if the
charge of the electric company per kWh
is ₱6.88?
