WEDNESDAY, APRIL 11TH

ODD DAY

EXPECT A QUIZ!

A QUICK WORD…

Since you are now responsible for vocab terms and questions to go along with the notes, you can expect a notebook quiz at the end of each assignment.

I WILL go over correct definitions/answers with you in class before the quiz.

However, it is YOUR job, not mine, to make sure that you have the correct definition. Your classwork grades will be dependent on completeness, citations and effort. NOT CORRECTNESS.

You can expect a notebook quiz before we begin chapters 19 and 20. That means April 19th and 20th. W

UNIT 6: ELECTRICITY

Chapters 17 - 20

CHAPTER 17:ELECTRIC FORCES AND FIELDS Objectives:

Understand basic properties of electric charge Differentiate between conductors and insulators

and the 3 methods of chargingCoulomb’s LawElectric Field strength

BASIC PROPERTIES OF ELECTRIC CHARGE: Two types of charge carriers: protons

(positive) and electrons (negative). Their charge is conserved and quantized. Question 1: What is the charge/mass of a

proton? An electron? Include units!Question 2: Who figured this out? How?

There are two types of materials: conductors and insulators.

Three ways to charge an object: contact, induction and polarization. Question 3: What methods of charging work

for what materials?

ELECTRIC FORCE AND COULOMB’S LAW: Coulomb’s Law describes the FORCE generated

by two electric charges separated by a distance:

Question 4: What do each of these variables stand for? What are the units?

Question 5: Write a word problem for your new equation! (Check out the book if you need some examples.)

Electric Force is a field force, much like gravity. Question 6: Which field force is stronger, gravity or

electric force? What do they have in common?

THE ELECTRIC FIELD The electric field is represented with the

following equation which supposes that a small, positive test charge (q0) is brought in to test the strength of the field made by q.

Question 7: What is the equation for the electric field strength from a point charge?

Electric field lines always point from a positive charge to the negative charge. Question 8: Draw the electric field lines for a:

a) +3 C charge and a -6 C charge at a distance, r. b) +3 C charge and a +6 C charge at a distance, r.

ONE LAST THING… Conductors in electrostatic equilibrium

follow four main rules:1. The E-field is zero inside the conductor2. Any excess charge is on the surface3. The E-field just outside the conductor is

perpendicular to the surface4. If the surface is irregular, the majority of

the charge will be at the sharp points. Question 9: Draw this for both a sphere

and an irregular shape of your choice.

CHAPTER 18:ELECTRICAL ENERGY AND CAPACITANCE

Objectives:Define and compute electrical potential

energy for various charge distributionsDistinguish between electrical potential

energy, electric potential and potential difference

Calculate the capacitance of various devices and how much energy is stored in a capacitor

ELECTRICAL POTENTIAL ENERGY There are two equations for electric

potential energy: In a uniform electric field:

For a pair of charges:

Question 10: What do each of the variables stand for? What are their units?

WHAT’S THE DIFFERENCE? (BETWEEN ALL THE POTENTIAL, OF COURSE!)

It is important to understand the difference between electric potential and potential difference. Question 11: What is this difference? (Explain in

your own words!) There are three equations for potential

difference. General: In a uniform electric field: - E∆d Between a point charge and a point charge at

infinity: Question 12: What do each of the terms mean?

What are their units?

CAPACITANCE Capacitance is used in a lot of electric circuits,

from cars to radios. The most general equation that represents it is:

In some cases, capacitance takes place in a vacuum. That is defined as:

Question 13: What is capacitance dependent on? Question 14: How do you use a capacitor in a circuit?

You can relate the electric potential of a circuit to the capacitance though:

Question 15: What do each of the variables in these 3 equations stand for? What are their units?

Understand and be able to calculate resistance. ΔV = IR

Relate and calculate electric power to known terms. P = IΔV = I2R = ΔV2/R

Interpret and construct circuit diagramsDifferentiate and calculate equivalent

resistance of resistors In series: Req = R1 + R2 + R3 + … In parallel: 1/Req = 1/R1 + 1/R2 + 1/R3 + …

Differentiate and calculate equivalent current In series: 1/Ieq = 1/I1 + 1/I2 + 1/I3 + … In parallel: Ieq = I1 + I2 + I3 + …

Understand and apply the concept that magnets can induce a current (p. 776)
