#1 - FILL IN THE BLANKS
- Electricity is the movement of
__________________ from one point to another.
- Voltage is measured in
__________________.
- A(n) __________________ is a material
that easily allows electricity to flow through it.
- Electric current is measured in
__________________.
- __________________ is a material’s opposition to the flow
of electricity.
- A(n) __________________ is a material
that conducts electricity in certain conditions but doesn’t conduct in
other conditions.
- Electrons have a __________________
charge.
- __________________ states that a
voltage drop across a circuit is equal to the resistance times the
current.
- Resistance is measured in
__________________.
- AC stands for __________________ __________________.
- DC stands for __________________
__________________.
- The most common/famous semiconductor
is __________________.
- A(n) __________________ is a material
that does not allow electricity to flow through it.
- A house plug provides __________________
current.
QUESTION #2 -
EQUATION MANIPULATION
Isolate
for x in each of the equations below.
Remember that letters that are side by side as actually being
multiplied together.
|
a)
p = xa
b)
xt = c
c)
34 + u =
x
d)
x + y =
V
e)
g = 2x
f)
h = 3x +
4
g)
2x = b +
x
h)
g + 4x = 2x + 3
i)
abx/2 = 6
j)
ax + j =
bt
|
Reminders:
1-Group
all terms with an x into one term.
2-Place
that term alone on one side of the equal.
3-Isolate
x.
