A coil of wire through which a current passes A device consisting of an electromagnet between 2 permanent magnets that can detect an electric current This device converts mechanical energy to electrical energy This device converts electrical energy into mechanical energy = power / voltage = I (amps) x R (ohm) And what this formula is called A build up of electric charge The release of built up charge When an electric or magnetic field is generated without contact A series of resistors all wired along a single path for current A series of resistors that each have their own path for current and each reduces the overall resistance of the circuit The third prong of a plug and lightning rods are both this: a word that means excess charge is channeled into the earth The region around a magnet or wire transmitting current where the force is exerted and felt When a current passes through a wire wrapped around a nail it is a temporary magnet called a Current comprised of a single direction of flow: as generated by a battery Current that switches direction as it flows: as carried by power lines and into our homes A device that that changes how much voltage there is. Found at power substations and outside homes on power lines A movable magnet that is free to rotate in the presence of a magnetic field Attraction or repulsion of charges Where magnetic charges are strongest The potential difference in positive and negative charges across a wire Units for Current Resistance Power Home power use Voltage Resistance and current have a _____________ relationship Current and voltage have a__________relationship A closed pathway for current to follow consisting of wires, a switch, resistors, and a battery or other power source In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction and so can convert AC to DC Add iron to the core Add more loops Make the loops closer together Add more current A group of atoms in a material that act like a small magnet.  In a substance that is not magnetized these point in random ways.  In magnets, all are lined up
