Electricity and Magnetism

Define Resistance

• Resistance is the ability of a material to conduct electricity without any hindrance.
• The tendency of a material to oppose the flow of electrons through it.

• Resistance is the measure of the voltage drop across a circuit.
• Resistance is the rate at which electric energy is converted into heat in a circuit.

Define Current

• The rate of change of electric charge
• The resistance in an electric circuit
• The potential difference between two points
• The movement of electric charge in a single direction.

Define Voltage Difference

• The flow of electrons in a circuit
• The resistance in an electric circuit
• The brightness of a light bulb in a circuit
• The push that causes charge to move.

Define Static Electricity

• Area surrounding charged particles/objects within which a force can be exerted on other charged particles/objects.

• The study of magnetic fields
• A charge imbalance that results in the buildup of excess electric charge in an object.

• A type of kinetic energy

Define Insulator

• A material that easily conducts electricity
• A Material that blocks the flow of the e- through them.

• A substance that allows the flow of heat without resistance
• A component that enhances the flow of electricity

Define Conductor

• A conductor is a type of musical instrument
• A material that allows e- to flow easily; readily conduct electric charge.

• A material that blocks the flow of the e- through them.

• A conductor is a material that absorbs light

Define Electrical Fields

• Electrical fields are static and do not interact with other particles.
• An area surrounding charged particles/objects within which a force can be exerted on other charged particles/objects

• Electrical fields are only present in conductive materials.
• Phenomenon where objects placed in a strong magnetic field become magnetized due to the poles within their atoms aligning.

Define Fuse

• A fuse is a type of food ingredient
• A material that allows e- (electricity) to flow easily; readily conduct electric charge.

• A fuse is a type of candle used for lighting
• A small piece of metal within that melts when overheated to open the circuit and prevent current from flowing.

Define Induction

• The transfer of electrons through an electric field working over a distance.

• An electric discharge of energy from storm clouds

• The process of removing excess charge on an object by transferring e- to another object to neutralize the electrical imbalance

• particles with no charge found inside the nucleus of an atom

Define the Law of Conservation of Charge

• Electric charge can be created or destroyed
• The total electric charge in a system can change randomly
• Electric charge is not conserved in nature
• Charge cannot be created or destroyed; only transferred
