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 11 – The Multimeter
(3:53) a)
A ___________________
is a tool that allows you to measure a variety of attributes about a circuit. b)
______________,
_____________ and ______________ are the most important attributes that your multimeter needs to be able to measure. c)
The cables that plug
into the multimeter have _____________
_____________ at the end of them. It is these that you plug into your
circuit to check an attribute. d)
By placing each test
probe on a different _____________ of the battery, we can measure its
voltage. Beginner Electronics 12 – Schematic Basics (5:14)
a)
A _______________ is
basically a blueprint of a circuit that we want to create. At school,
we tend to use the term circuit diagram instead. b)
On a schematic, the
lines connecting different components are ____________. c)
The symbol with 4
vertical lines represents a ______________. (Of course, in another
circuit, the symbol could be flipped on its side and all lines would be
horizontal instead.) d)
On the battery symbol,
the ______________ terminal is the side with the short line that looks like a
vertical minus sign. e)
The squiggly line symbol
represents a ______________. f)
An _____________’s
symbol consists of a triangle pointing towards a line along with arrows
pointing away from the symbol. g)
Associate each
name/description with its symbol below: Three wires connecting ______ Battery ______ Resistor ______
Note: Avoid using the symbol
6 as it causes confusion. Use symbols 1 or 2 when wires either connect
or don’t connect. Beginner Electronics 13 – Switches (5:57)
a)
SPST stands for
_____________ _____________ ______________ _____________. b)
Associate each switch
position with its symbol below: Switch in ON
position ______
a) Conventional current leaves the positive terminal of the
battery, goes through a resistor and then goes through an LED before
returning to the battery’s negative terminal. b) Conventional current leaves a 9V battery and goes through a 220 ohm resistor (R1). The current then has a fork
with one branch containing an LED and the other branch containing another 220 ohm resistor (R2). Both branch then merge
together and return the current to the battery. QUESTION #1 SOLUTIONS BELOW
