Topics 1-3 in Electricity
|Flow of charged particles
|Parts of an atom
|Proton, neutron, electron
|Build up or imbalance of electric charges within or on the surface of a material.
|Steady flow of charged particles
|gaining or losing an electrical charge to achieve balance with objects around it
|connect object to earth to drain excess electrons
|Uses ions (positive or negative atoms) to neutralize objects
|equal positive and negative charge
|more protons than electrons
|more electrons than protons
|Law of charges: Opposite charges
|Law of charges: Similar charges
|Law of charges: neutral and charged
|one positive and one negative terminal. 1.5V
|multiple positive and negative terminals linked together
|slows the flow of electrons
|load that converts electrical energy to heat and light
|converts electrical energy to other types of energy
|converts electrical energy to mechanical (movement) energy
|conductor that allows electrons to flow
|one pathway for electrons to flow
|multiple pathways (called branches) for electrons to flow
|another name for voltage
|the "pressure" or "power" that electrons carry
|the amount of electrons moving through a conductor
|R= V/ I
|used to measure current
|used to measure voltage
|used to measure resistance
|metal contact is broken. Electricity will not flow
|Metal to metal contact is intact and electricity will flow
|Resistance of good conductors
|Resistance of insulators
