a circuit that connects two or more objects so that the current flows along a different path to each object
What is a parallel circuit
100
material that has a magnetic field around it and so attracts metals containing iron, cobalt, or nickel.
What is magnet
100
an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.
What is static electricity
100
tiny particle that is part of the nucleus of an atom; has no electric charge
What is neutron
200
a circuit that connects two or more objects, one after the other, so that the current flows in a single path to all objects
What is series circuit
200
the process of creating a current in a circuit by charging a magnetic field
What is Electromagnetic induction
200
the force around moving electrons, whether they are moving in a straight or circular path
What is electric field
200
a tiny particle that is part of the nucleus of an atom; has a positive electric charge
What is proton
300
an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.
What is alternating current
300
a temporary magnet made when electric current flows through a wire wrapped around an iron or steel core
What is electromagnet
300
a basic property of matter that can be positive or negative and that changes when matter gains or loses electrons
What is electric charge
300
a tiny particle that moves around the nucleus of the atom; has a negative electric charge
What is electron
400
an electric current flowing in one direction only.
What is direct current
400
one of the two points, such as the ends of a magnet that have opposing magnetic qualities
What is magnetic pole
400
a device for reversing the direction of flow of electric current.
What is commutator
400
the charges given off my an electron
What is negative charges
500
material through which electric current passes easily
What is conductor
500
a space around a magnet where the force of the magnet acts
What is magnetic field
500
an effective resistance that is used to describe the resistive parts of the impedance of certain electrical components
What is equivalent resistant
500
a group of atoms whose magnetic fields are lined up with one another
