BASIC ELECTRONICS Today, you will continue viewing videos and fill out a worksheet
as you listen. Afterwards, you will have a few exercises to complete. Link to videos:
TASK #1 - VIDEOS & WORKSHEET Watch the
videos (link above) and fill in the worksheet as you go. Beginner
Electronics 6 – LEDs (4:04) a)
LED stands for ______________ _____________
_____________. b)
An LED almost always requires a
_______________ in series with it because it cannot handle too much
current. Adding this device lowers the amount of current that goes down
the wire with the LED and hence protects it. c)
On an LED, the longer lead (anode) should be
connected to the _______________ terminal of a battery. d)
On an LED, the shorter lead (cathode) should
be connected to the ________________ terminal of a battery. Beginner
Electronics 7 – How much resistance? (6:19) ·
You can skip this video. It is simply
too advanced for where we are at at this point. ·
Know that for lighting an LED with a battery
operating at 6 volts, we use about a 500 ohm
resistor. However, a 1000 ohm resistor would
also work, but would give you a dimmer LED. You do not need to remember
this. Beginner
Electronics 8 – First Circuit! (3:33) ·
The goal of this video is simply to see the
LED get turned on in a very simple circuit. You should notice that the
LED has to be connected in the correct direction. If you connect it
backwards, it simply will not work. a)
The resistor can be attached on the
______________ side or the ______________ side of the LED. ·
Notice that despite having a very simple
3-device (battery, LED, resistor) circuit, holding the components together is
already challenging. It’s impossible to hold a circuit together that
has just a few more devices in it. Beginner
Electronics 9 – Necessities! (4:12) a)
A _____________ ______________ is a component
that holds one or more batteries in place and provides a dependable
connection between each terminal and a wire. b)
A _______________ (and a button) is a device
that allows you to toggle a circuit between an open state and a closed
state. c)
A ________________ is a device that allows us
to conveniently connect an advanced electronic circuit together. d)
_______________
is a piece of conducting metal stretched out into a thin flexible
thread. It is used to connect different components together. All
circuits consist of many of these pieces. It is covered by an
insulating rubber material. Beginner Electronics 10 – Breadboards (7:57) a)
The top and bottom rows are called
_______________ ________________ (or buses). b)
All holes in the very top row are
__________________ to each other. The same goes for the holes in the
next row. Similar for the bottom two rows. c)
In the central area, the 5-hole columns
have holes that are connected together.
a)
Are the two green wires connected to each
other? ______ b)
Are the two pink wires connected to each
other? ______ c)
Are the two orange wires connected to each
other? ______ d)
Are the two yellow wires connected to each
other? ______ e)
Are the two red wires connected to each
other? ______ f)
Are the two blue wires connected to each
other? ______
Use an
internet search to discover the voltage of each battery type.
