Electricity	Resistance	Device	Electromagnet	Transformer
100 Electricity Electrical energy and the movement of change	100 Kirchhoff's Voltage Law The law states that the voltage gains are equal to the voltage drops in a complete path in a circuit	100 Superconductors Special materials with no electrical resistance	100 Solenoid Coiled conductor	100 Faraday's Ring Device that demonstrates electromagnetic induction
200 Electrical Power The rate at which electrical energy is generated or transformed	200 Kirchhoff's Current Law The law states that the current entering a junction is equal to the current exiting a junction in a circuit	200 Ohmmeter Device used to measure electrical resistance and should be connected in parallel to a circuit that is switched off	200 Electromagnet Device that produces a magnetic field as a result of an electric current	200 Electromagnetic Induction The production of electric current in a conductor moving through a magnetic field
300 Electrical Energy Measured in units of kilowatt hours (kWh) for homes and megawatt hours (MWh) for power plants	300 Electrical Resistance Property of all matter that describes how difficult it is for an electric current to travel through the matter	300 Magnetic Field Region of space around a magnet that causes a magnetic force on magnetic objects	300 Motor Principle Principle states that a current-carrying conductor experiences a force perpendicular to both the magnetic field and the direction of the electric current	300 Lenz's Law The law states that if a changing magnetic field induces a current in a coil, the electric current is in such a direction that its own magnetic field opposes the change that produced it
400 Electric Potential Measure of how much electric potential energy is associated with charges	400 Resistors Devices with specific electrical resistance	400 Oersted's Principle Principle states that a charge moving through a straight conductor produces a circular magnetic field around the conductor	400 Split Ring Commutator Part of a DC motor that interrupts the circuit	400 Alternating Current Electric current that periodically reverses direction
500 Direct Current The flow of electrons in one direction only	500 Ohm's Law The law states that the voltage in a conductor is proportional to the current if the temperature remains constant	500 Right-hand Rule The rule that if you hold a straight conductor in your right hand with your right thumb pointing in the direction of the conventional current, your curled fingers will point in the direction of the magnetic field lines	500 DC Electric Motor Motor consists of a rotor and a stator	500 Transformer Electromagnetic device that can raise or lower voltage
