3. Resistors
A resistor is a component that
resists the flow of current. It's
one of the most basic
components used in electronic
circuits, you get an idea of how
small they are.
5. Capacitors
Next to resistors, capacitors are
probably the second most commonly
used component in electronic
circuits. A capacitor is a device that
can temporarily store an electric
charge.
7. Diodes
A diode is a device that lets current flow in
only one direction. A diode has two
terminals, called the anode and the
cathode. Current will flow through the
diode only when positive voltage is applied
to the anode and negative voltage to the
cathode. If these voltages are reversed,
current will not flow.
10. Transistors
A transistor is a three-terminal device
in which a voltage applied to one of the
terminals (called the base) can control
current that flows across the other two
terminals (called the collector and the
emitter). The transistor is one of the
most important devices in electronics.
12. Integrated Circuits
An integrated circuit is a special component
that contains an entire electronic circuit,
complete with transistors, diodes, and
other elements. Integrated circuits are the
building blocks of modern electronic
devices such as computers and cellphones.
14. What is a circuit?
Combination of electronic parts, wires connected between
power sources. It's like a physical program.
15. What is a breadboard?
What are they good for?
Creating , organizing, and prototyping a circuit.
16. What are LEDs?
Light Emitting Diodes
Diode Symbol + Arrows for light
Points to ground
17. LED Circuit
1 LED Plus resistor
Why have a resistor?
Current, limiting.
22. What are resistors?
Resistors provide a specific amount of resistance to a path in a
circuit or wire. Ohm's law is used to calculate the
properties related to resistance.
Ohm's Law: I = V/R, V=IR
I = Current measured in Amps
V = Voltage measured in Volts
R = Resistance measured in Ohms
Resistors are color coded.
26. What are capacitors?
Capacitor is two separated charges.
Known charge up time.
Know discharge time.
Two major kinds
• Electrolytic, asymmetric, bipolar
• Ceramic, symmetric
