Electronics is
• The branch of science and technology that
deals with controlling electricity.
What is electricity?
• The word electricity comes from the Latin
electrum, which comes from the Greek
word ἤλεκτρον (elektron), meaning amber.
• Origin of the Greek word is unknown, but
may have come from Phoenician word
elēkrŏn, meaning ‘shining light’.
• Phoenician is similar to Hebrew and in
Hebrew, el means God.
• The original meaning of electricity may
literally be ‘power of God’.
Electric vs. Electronic
• Electricity = movement of charge (usually
electrons)
• Electric circuits and systems are used to
manage power.
• Electronic circuits and systems are used to
manage information.
Why is electronics important?
• Moving objects have kinetic energy and
can be used to do work, therefore,
electricity can be used to do work for us.
• What do we use electricity for?
• What do we use electronics for?

If you continue in electronics, you can design,
build and repair electronic systems
Electronics is
• The branch of science and technology that deals
with controlling electricity.
• Arguably the most important contributor to the
development of our modern world.
• Of huge importance to modern communication,
energy, industry, medicine, travel, defense,
entertainment, in short, our modern way of life.
• The largest single industry in the world.
• An excellent career choice.
• Sadly, a mystery to most people.
• Lots of fun!
