- 1electrons flow in one directiondirect current,
batteries - 2pushes the electrons back and forth, changing the direction of the flow several times per secondAC alternating current, lights in house
- 3The transfer of electrical energy through a conductorhappens at nearly the speed of light
- 4Increasing the current through a wire:causes the magnetic field around the wire to increase
- 5A ferromagnetic core:increases the strength of an electromagnet because it contains magnetic domains that align under the influence of a magnetic field
- 6The strength of an electromagnet can be:increased by adding a ferromagnetic core
- 7All magnetic fields are created bymoving electric charges
- 8a magnetic field exerts a force on a charged particle:that is perpendicular to both the magnetic field and the particle's direction of travel.
- 9Adding a light bulb to a series circuit willincrease the total resistance cuz it has to go thru it, you add it up
- 10Adding a light bulb to a parallel circuit will:decrease the total resistance
- 11The total current through a parallel circuit:increases if more light bulbs are added to the circuit
