100
This states that all like charges repel, or push away, and opposites attract.
What is the Law of Electric Charges?
100
The energy of electrical charges
What is electrical energy?
100
Formula(s) to Ohm's Law
What is the law that shows that R=V/I or V=I*R ~ voltage (V), current (I), resistance (R)
100
The 3 essential parts of a circuit
What is an energy source, wires, and a load
100
The electric charge at rest in an object
What is Static Electricity
200
The two things that the size of the electric force depends on.
What is 1) the amount of charge on each object and 2) the distance between the two charges.
200
(Part A) The rate at which charges pass a given point. (Part B) Unit it is expressed in
What is an Electric Current and an Amperes (Amp)?
200
Symbol for resistance in ohms
What is the Omega (Ω)
200
Used to open and close a circuit, controlling the flow throughout the circuit.
What is a switch
200
If the resistance of an object is 4 , and the current in the object is 9 A, what voltage must be used?
What is 36 V
300
Electrons are held in the atom because of this (How are electrons held in atoms).
What is the Law of Electric Charges (attraction between protons (positive charge) and electrons (negative charge). Because protons and electrons have opposite charges, they are attracted to each other. Without this attraction, electrons could not be held in atoms.
300
The Two Different Types of Currents (Describe each).
What is an Alternating Current (charges continually shift from flowing in one direction to flowing in the reverse direction) and Direct Current (charges always flow in the same direction).
300
The voltage if the current is 2 A and the resistance is 12 Ω
What is 24 V
300
The Two Different Types of Circuits (name and describe).
What is a Series Circuit (a circuit in which all parts are connected in a single loop) and a Parallel Circuit (a circuit in which loads are connected side by side. Charges in a parallel circuit have more than one path on which they can travel).
300
The Difference Between Conductors and Insuators
What is An electrical conductor is a material in which charges can move easily, and an electrical insulator is a material in which charges cannot move easily
400
This detects charged objects. (Explain how it works, too)
What is an Electroscope. When the electroscope is not charged, the leaves hang down. When it is charged, the leaves repel each other, or spread apart.
400
The Definition of Voltage and its Relationship with Energy AND a Current
______________is a measure of how much work is needed to move a charge between two points. The higher the voltage is, the more energy is released per charge.The greater the voltage is, the greater the current is
400
The formula for electrical energy and unit most often used to express it.
What is electrical energy = power × time, or E = P × t ~Unit: kilowatt-hours (kWh)
400
Four Electrical Safety Tips
What is 1. Make sure the insulation on cords is not worn. 2. Do not overload circuits by plugging in too many electrical devices. 3. Do not use electrical devices while your hands are wet or while you are standing in water. 4. Never put objects other than a plug into an electrical outlet.
400
Voltage is the opposition to the current by a material (True of False) Give the correct term
What is False. RESISTANCE is the opposition to the current by a material.
500
Static electricity builds up on clothes in a dryer (describe what happens)
What occurs when clothes in a dryer are charged by friction, therefore, negative charges are lost as other clothing items gain the lost charges. When the dryer stops, the transfer of charges also stops; because clothing is an insulator, the built up charges stay on the clothes.
500
~1. Batteries used in cameras ~2. Electric currents in outlets at home (Examples of.....)
What is an example of a 1. Direct Current and a 2. Alternating Current
500
Three ways to conserve energy
What is 1. Use fan instead of air conditioning 2. Turn off lights when not using them 3. Replace items of high power ratings with items of low power ratings
500
The purpose of Circuit Breaker and Fuses
What is used to PROTECT AGAINST CIRCUIT FAILURES
500
Comparison and Contrast Between an Electrolyte and an Electrode
What is ~An Electrolyte is a mixture of chemicals that allows charges to flow ~An Electrode is the part of a cell through which charges enter or exit ~Chemical changes between the electrolyte and the electrodes convert chemical energy into electrical energy. (Both are used to create electrical energy)
