4. Instruction:
The birth of electricity has extremely
changed the lives of people. To
investigate the mysterious person
behind the existence of electricity, the
students should match the picture with
the correct word. Each correct
association of the word and the picture
can lead to the solution of the puzzle.

5. At the end of the session,
the students are expected to:
Describe and explore ohm’s law principle;
Solve electrical calculation of basic electric
circuit using ohm’s law; and
State the importance of Ohm’s law principle
in real-life application.

7. Instruction:
Using cutinized papers, write some
examples of devices and
appliances in our home that use
electricity. Paste your answer on
the intended manila paper of your
group.
8. Based on all the things written,
what are some common household
appliances that use electricity?
How does it power electronic
devices and appliances in our
homes?

11. Instruction:
Each group must solve the
following word problem about
ohm’s law principle and choose a
representative to present the
output.
12. Group 1: Problem-solving about voltage
Problem #1: When a current of 3 amperes run
through the coiled heating element of a stove, the
resistance of the element is 80 ohms. What is the
voltage of the stove?
Group 2: Problem-solving about current
Problem #2: A frying pan is connected to a 110-volt
circuit. If the resistance of the frying pan is 10 ohms,
how many amperes does the frying pan draw?
Group 3: Problem-solving about resistance
Problem #3: A lightbulb carries 0.5 A when 4 volts is
impressed across it. What is the resistance of the
filament in the lightbulb?
