resistance (R) - ohm (omega)
Units and Symbols
Components and Circuit Diagram Symbols
Let's Build Some Circuits!
Break out the breadboard!
voltage (V) - volt (V)
current (I) - ampere (A)
energy (E) - joule (J)
power (P) - watt (W)
time (t) - second (s)
capacitance (C) - farad (F)
charge (q) - coulomb (C)
potential difference (delta V) - volt (V)
Lesson 1, 2, and 3
Resistor, Potentiometer, Photocell, Capacitor, Speaker, Diode, SCR, Transistor, LED
V = IR
The SI unit for power is
named after him: Watt (W)
Founder of electromagnetism
The SI unit for work/energy
is named after him: Joule (J)
Coulombs Law: FE = kq1q2/r2
Discovered electromagnetic induction
For Mr. Reding's AP Physics
charge "pump" that pushes charges and causes current
"clog" in pipes that
"pipe" for charges to move through
metal plates that act
like "savings account"
to store charge
one-way "valve" that emits light when current goes through it
special resistor that glows
when current goes through it
variable resistor acts as "dam" that can open or close its door
acts as "train station" used for amplifying or switching current
"traffic signal" for current
chip, or miniature circuit
battery, light bulb (acting as resistor), wires
Ohm's Law: V = IR
as resistance goes up, more voltage
is needed to cause current
positive charges are pushed out
of the positive end of a battery and
attracted to the negative end
