19. SCREWDRIVER - is a hand
tool used for driving
(tightening or loosening)
screws. It consists of a
handle, a shaft, and a tip
that fits into the head of a
screw. Screwdrivers come in
different shapes and sizes
to match various screw
types.

20. Common
Types of
Screwdrivers

21. FLAT HEAD
SCREWDRIVER -
Has a flat,
straight tip and is
used for slotted
screws.

22. PHILIP
SCREWDRIVER- a
cross-shaped tip,
designed for Phillips
head screws, which
provide better grip
and prevent slipping.

25. PLIERS - are a hand tool
used for gripping,
bending, cutting, and
holding objects firmly.
They have two handles, a
pivot point, and jaws
designed for different
tasks. Pliers are
commonly used in
electrical work.

26. Common
Types of
Pliers

27. COMBINATION
PLIERS /
LINEMAN’S PLIER
– Multi-purpose
pliers used for
gripping, bending,
and cutting wires

28. Long Nose Pliers –
Have long, narrow
jaws for reaching
tight spaces and
bending small
wires.

29. DIAGONAL
CUTTING PLIERS
– Designed for
cutting wires and
small pins close
to surfaces.

35. VOM (Volt-Ohm-Milliammeter)
- commonly known as a “MULTI-
METER” is an electrical testing
device used to measure voltage
(volts), resistance (ohms), and
current (milliamps). It helps
electricians and technicians
diagnose and troubleshoot
electrical circuits, components,
and devices.

36. Types of
Multi-tester

37. ANALOG
MULTIMETER – Uses
a moving needle to
display
measurements,
providing a
continuous reading.

38. DIGITAL
MULTIMETER –
Displays readings
on a digital screen,
offering higher
accuracy and
easier readability

somewhat clear but
lacks some details or
has small inaccuracies.
The drawing is unclear,
incomplete, or has
major proportion
issues.
The drawing is
unrecognizable, very
messy, or missing.
2. Function
Explanation (5 pts)
The function is clearly
and accurately
explained using correct
terminology.
The function is mostly
clear but has minor
errors or missing
details.
The function is
somewhat
understandable but
lacks key details or
accuracy.
The explanation is
unclear or has major
errors.
