The amount of charge passing a point in a given time interval is
Opposite charges ______
Like charges _______
The amount of potential energy stored in a battery is measured in _______
A material in which electrical charges do not move freely
The heating wire in a toaster is low/high resistance
Electrical wiring is low/high resistance
A lightbulb filament is low/high resistance
If the voltage goes up, the current (increases, decreases)
If the resistance decreases, the current (increases, decreases)
An accumulation of electrical charges on an insulator is
In order to separate positive and negative charges, ______ must be added
Conductors (will/will not) hold a static charge
Give 2 examples of an insulator
Plastic, glass, wood, rubber
The amount of energy which is changed into heat and light as an electrical current flows through the material
Electrical energy which is converted into heat, light, and sound when the electricity leaves the object
What is the formula for Ohm’s Law?
R = V/I
The small particles that make up matter
What method is involved when charges in an uncharged metal object are rearranged without direct contact with a charged object?
Method of charging in which electrons are wiped from one object to another
Material that allows charges to move freely
The force between two charged objects
The region around a charged object where a force is exerted on other objects
Expressed in Amps
What are the 3 parts in a circuit?
Voltage, resistance, current
What is the current when a 12-volt battery is connected through a resistance of 240 ohms?
What voltage produced a current of 100 amps with a resistance of 10 ohms?
Chapter 20 Electricity.
Chapter 6 Electricity.
What is an electric charge? Describe the structure & charges in an atom. Charge- physical property Charged objects exert a force- push or pull-
WELCOME BACK MINIONS Place books on floor. Have only notebook and writing utensil on the desk.
Chapter 17: Introduction to Electricity Review. a)law of electric charges (like charges repel and opposite charges attract) b)electric force (the force.
Electricity. Charges Atoms contain particles called protons, neutrons, and electrons. Protons (+) Electrons (-) Neutrons (0)
What do you think the term Electric Charge means?
Electricity Foundations of Physics. Electricity The movement of charge from one place to another Requires energy to move the charge Also requires conductors.
Electricity. whether two charges attract or repel depends on whether they have the same or opposite sign unit of measurement for charge is the coulomb.
Chapter 21 Electricity. Opposite charges attract, like repel Charged objects can cause electrons to rearrange their positions on a neutral object.
1 Electricity Chapter Charged objects Neutral Equal positive and negative charges Positive Fewer negative charges (lost electrons) Negative More.
Electric Charge and Static Electricity
Matter is made up of small particles called atoms. Atoms are made up of smaller, sub-atomic particles called protons, neutrons, and electrons. Sub-atomic.
Electricity A. Electric Charge 1. Static electricity is the accumulation of excess electric charges on an object. a. More e¯ = negative charge b. More.
Ch. 5 Sec.1 Notes. Electric Charges The law of electric charges states that like charges repel and opposite charges attract. _ _ _.
Chapter 7 Electricity. An atom is the basic unit of matter and is made of protons, neutrons, & electrons – protons: + charge – electrons: - charge – neutrons:
CHAPTER 1 ELECTRICITY. The amount of charge flowing past a point in a given time CURRENT.
Warm-Up: 1. What does it mean for a particle to have a “charge”? 2. When do you observe static electricity?
Electricity! It’s Shocking!!. Remember the electron??
CHAPTER Static Electricity ElectricityCircuits Measurements & Units Do the Math 600.
