Things you need to know:

- Mr. Cooper is available for extra help after school every day upon request.
- If you are absent for one day, get the notes you missed from another student, and the lab you missed from Mr. Cooper as soon as possible.
- If you are not sure what to do, ask your instructor. There are no stupid questions.
- Request extra help before you fall behind.

Notes on Mr. Atom:

- All materials are made of atoms.
- Protons and Neutrons reside in the Nucleus.
- Electrons orbit around the nucleus at the speed of light.
- Current flow is the movement of free electrons.
- Like charges repel, unlike charges attract. (Coulomb’s Law)

More notes on Mr. Atom:

- The number of electrons in the valence shell determines the electrical properties.
- Conductors have 1 – 3 valence electrons.
- Semiconductors have 4 valence electrons.
- Insulators have 5 – 8 valence electrons.
- Balanced atoms have an equal number of protons and electrons.
- An atom that loses an electron is a positive ion. An atom that gains an electron is a negative ion.

Mr. Ohm is our good friend!

- Ohm’s Law defines the relationship between Current, Voltage, and Resistance.
- Ohm’s Law states that current is directly proportional to voltage and inversely proportional to resistance.
- Current flow is the movement of free electrons (from negative toward positive). The unit for current flow is the Ampere. The letter “I” stands for Current. Ex: I = 1.5 A.

Mr. Ohm is so cool!

- Voltage is the force that moves electrons. The unit for voltage is the Volt. The letters “E” and “V” both stand for Voltage.
- Resistance is the opposition to current flow. The unit for resistance is the Ohm (shown as the Greek letter Omega). The letter “R” stands for resistance.
- Formulas you need to know forever: E=I*R, I=E/R, R=E/I.

Mr. Watt is also very cool!

- P = Power in Watts. P=I*E
- Here’s those groovy magic pies again!
- Note: E = V
- Note: There are three power Formulas… P = I*V, P = I^2*R, P = E^2/R

Metric Prefixes are great!

- Mega = 1,000,000 = 1 EE 6 = M
- Kilo = 1,000 = 1 EE 3 = K
- (Units Volt, Ohm, Amp have no exponent.)
- milli = 0.001 = 1EE-3 = m
- micro = 0.000 001 = 1 EE-6 = u
- nano = 0.000 000 001 = 1 EE-9 = n
- pico = 0.000 000 000 001 = 1 EE-12 = p

LOVE YOUR METER!

- An ammeter must be connected in series to measure current!!
- A voltmeter is connected in parallel to measure voltage!
- An ohmmeter must never be connected to a “live” circuit when measuring resistance!!

Series circuits are very exciting!

- Current flow is constant in series.
- Voltage drops add up to the total voltage.
- 1. Rt = R1+R2+R3
- 2. It = Et/Rt
- 3. It = IR1 = IR2 = IR3
- 4. ERx = IRx*Rx
- 5. PRx = IRx*ERx

Calculate the EIRP values!

- 1. Rt=R1+R2+R3=3K-Ohms
- 2. It=Et/RT=4mA
- 3. It=IR=IR2=IR3=4mA
- 4. ER1=IR1*R1=4V, ER2=IR2*R2=4V, ER3=IR3*R3=4V
- 5. P=I*E=16mW each=64mW total

Parallel circuits are super awesome!

- Voltage drops in a parallel circuit are constant.
- Branch currents in a parallel circuit add up to the total current.
- 1. Et=ER1=ER2=ER3
- 2. IRx=ERx/Rx
- 3. It=IR1+IR2+IR3
- 4. RT=ET/It
- 5. PRx=IRx*ERx

Calculate the EIRP values!

- 1. ET=ER1=ER2=ER3=12V
- 2. IR1=ER1/R1=1mA, IR2=ER2/R2=1mA, IR3=ER3/R3=1mA
- 3. It=IR1+IR2+IR3=3mA
- 4. Rt=Et/It=4K-Ohms
- 5. P=I*E=3mW each=9mW total.
- Check: RT=1/(1/R1+1/R2+1/R3)
