Conductors allow electrons to flow easily through them , therefore conduct electricity.
What is a conductor?
100
Ohms law states that the relationship of voltage , current and resistance is given by : V=IR
What is Ohms law?
100
Energy is the ability to work. Potential energy is the energy stored in an object.
What is the difference between Energy & Potential Energy?
100
Negative & Positive.
What are the two types of charges?
100
If one goes out they all go out.
If one of bulb's goes out in a Series Circuit what happens?
200
Insulators prevent electrons from flowing through them.
What is a insulator?
200
The property of material that slows down the flow of electrons and converts electrical energy into other forms of energy.
What is Resistance?
200
Either by a Multimeter or a Voltmeter.
How is Voltage/ Potential Difference measured?
200
They become neutral by gaining electrons.
How does positive charged objects become neutral ?
200
If one goes out the others are not affected.
What happen's if one of the bulb's in a Parallel Circuit goes out?
300
Copper.
What is an example of a conductor?
300
The amount of electrical potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per coulomb of charge at another point in the circuit.
What is Voltage?
300
1. Amount of charge separated. 2. Types of metals used for the electrodes.
How do you know the amount of voltage in a cell?
300
They become neutral from losing electrons.
How does negative charged objects become neutral ?
300
The total resistance of the circuit is decreased.
When more resistors are added to a Parallel Circuit what happens?
400
Plastic.
What is an example of a insulator ?
400
the continuous flow of charge in a complete circuit.
What is current electricity ?
400
It's measured in Joules (J)
How is Electrical Potential Energy measured?
400
Electrical charge is measured in Coulombs.
How is electrical charge measured?
400
The loads that are in Parallel have the same voltage.
What happens to the voltage in a Parallel Circuit ?
500
If a static charge is created on an Insulator , that charge remains held very nearly in one place and doesn't very far. But when there are extra elcetons in one location on a conductor the charge travels throughout the conductor.
What is the difference between Insulators & Conductors when you add a static charge?
500
An electrical component with a set amount of resistance that slows down current and transforms electrical energy into other forms of energy.
What is the resistor?
500
The greater the difference in potential energy the higher the energy of force that pushes the electrons.
What does the difference in Potential Energy do ?
500
1. Opposite charges attract. 2.Like charges repel. 3.Charged objects attract some neutral ones.
What are the 3 laws of Electric charge?
500
As more bulbs are added they increase the resistance in the circuit , therefore decreasing the total current in the circuit.
Why as you add more light bulbs to the Series Circuit the brightness decreases?
