Circuits

TermDefinition
schematic circuit diagram
open circuit the closed conducting loop is broken and no charge flows
closed circuit the closed conducting loop allows charge to flow
short circuit nothing slows down current because there is a direct path back to the battery (no resistance); can cause overheating, melting, etc.
current how many charges pass through a cross-section of wire in a certain amount of time
conventional current the idea that current flows from the positive side of a battery to the negative side
electron flow the idea that current flows from the negative side of a battery to the positive side (also called real current)
Coulomb the unit for charge; the amount of charge transported by a steady current of one amp in one second
filament the wire inside of a light bulb's globe that glows
globe the glass casing on the outside of a light bulb filled with gas
ribbed edge the metal portion of the light bulb that screws into a fixture or light bulb holder
base the conducting part at the very bottom of a light bulb
insulating material strip of material at the bottom of the light bulb that separates the ribbed edge from the base
cathode the positive terminal or electrode of a battery
anode the negative terminal or electrode of a battery
separator the barrier between the cathode and anode of a battery
electrolyte solution allows electrons to flow from the cathode to the anode inside of the battery
volts the unit for a battery's potential energy, or voltage
voltage a battery's potential energy
resistance property of a material to restrict the flow of charges
