Charge
What is Electrical Charge?
A charge produced by an excess or shortage of electrons.
What is a Conductor?
A material through which electrical charge can easily flow.
What is a Diode?
An electrical component that allows electrical current to flow in and out in a single direction.
What is Potential Difference?
The work needed to push a certain amount of electric charge between two points on a conducting pathway.
What is a Magnetic Field?
The area around a magnet in which the magnetic force can be felt.
What is Induction?
The transfer of electrical charge without contact between the materials.
What is an Insulator?
A material through which charge cannot easily flow.
What is an Anode?
A positively charged diode.
What is a Parallel Circuit?
An electrical circuit in which current can pass through more than one path.
What is a Magnetic Pole?
One of the two ends of a magnet where the force of attraction or repulsion is the strongest.
What is a Semiconductor?
A material that can act as a conductor or insulator based on its temperature.
What is a Cathode?
A negatively charged diode.
What is a Series Circuit?
An electrical circuit in which current passes through components that are one after the other.
What is an Electromagnet?
A magnet that can be switched off and on with electric current.
What is an electrolyte?
A substance that can conduct electrical current.
What is Resistance?
The ability of a material to resist the flow of electrical current.
What is Electromagnetic Force?
The force produced when an electrical current flows through a wire; it forms a magnetic field.
What is a Solenoid?
A coil of wire that behaves like a magnet when electric current passes through it.
