This document discusses basic electronic hand tools and how to use a VOM (volt-ohm-milliammeter) device. It defines what a VOM is and how it can be used to measure voltage, current, and resistance. It also explains the principles of series and parallel circuits and Ohm's Law, including the formulas that show the relationships between voltage, current, resistance, and power in an electrical circuit.
Some slides here were disorganized although I uploaded it on its good condition. Maybe some compression? or what? Howsoever, I think that it's readable and understandable enough.
1. A TV set, a stove and a flatiron are connected in series to a 220-V line. The resistance of the TV set is 20-ohms, the stove 50-ohms, and the flatiron 35-ohms. Find a) the total resistance, b) the amount of current flowing each device and c) the voltage drop across each device.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

18. What is VOM?
VOM/ Multi-tester= it is an electronic measuring device used
to measure voltage, current and resistance.
Voltage= it is an electrical pressure that moves the electrons
in wire. The unit is volt (V).
Current= it is a result of electrons in motion. The unit is
ampere (A).
Resistance= it is the property of material that opposes the
movements of electrons. The unit is ohm (Ω).
22. KINDS OF CIRCUIT
SERIES CIRCUIT- it is a circuit that has only one
path of current to flow.
PARALLEL CIRCUIT- it is a circuit that have two
or more path of current to flow.
COMPLEX CIRCUIT- a circuit that have series
and parallel connection.
23. OHM’S LAW PRINCIPLE
Ohm’s Law states that the current is directly
proportional to voltage and inversely proportional to
resistance.
• I=V/R
• V=I x R
• R=V/I
Power means rate of doing work.
• P= I x V
