glossary terms 2

  1. Electric
    • -a path in which electrons flow from a source
    • -because it is a circuit the electrons must return to the cycle through the circuit and get back to the terminal where they began in order for the circuit to function
  2. voltaic cell
    - an electrochemical cell that converts the energy from chemical reactions into electrical energy
  3. battery
    - multiple cells used in combination with each other to produce more energy
  4. electrode
    - an electrical conductor designed to be able to touch the non metallic portion of the circuit
  5. electrolyte
    -a chemical within cells that when voltage is applied becomes a conductor
  6. dry cell
    • -is one of the most commonly used types, including AA, 9-volt, and watch batteries.
    • -
  7. wet cell
    • - a rechargeable battery 
    • - precursor to the dry cell
  8. primary cell
    -a cell that can only be used once and is after that useless
  9. secondary cell
    - a cell that can be recharged and used multiple times
  10. fuel cell
    - a cell that generates energy through chemical reactions of fuel that is stored outside of the cell
  11. solar cell
    -a cell that converts energy from the sun into electric energy that can be used or stored
  12. terminal
    - one end of a battery that either stores electrons or attracts them
  13. switch
    - a mechanism within a circuit that controls whether or not the circuit functions
  14. open circuit
    - a circuit in which the switch is open therefore there is no direct route for the electricity to flow through the circuit
  15. electrical current
    - the flow of electric charge often through a metallic wire
  16. coulomb (c)
    • - the fundamental unit of electrical charge
    • - equivalent to 1 coulomb = 1 ampere per second
  17. ampere (A)
    - used to measure the charge of one section of a circuit
  18. elecrical resistance
    • R=potential difference divided by current
    • the amount of opposition for electric energy in a conductor
  19. resistor
    • acts to reduce current flow 
    • implements electrical resistance
  20. load
    - a component of a circuit that uses the
  21. potential difference (voltage)
    - the difference in electric potential between two points in a circuit
  22. volt
    - the difference of potential that would push one coloumb of current against one ohm of resistance
  23. circuit diagram
    - a diagram that shows the construction of a circuit in an organized and neat way, showing all routes and componentsImage result for circuit diagram
  24. series circuit
    -a series in which all loads are in series with eachother and there are no other routes
  25. parrallel circuit
    - a circuit where there are multiple routes for current to flow
  26. Ohm's law
    • describes how to find multiple aspects of a circuit or section of a circuit, like resistance, current, and potential difference.
    • I = frac{V}{R},
  27. Ohm (Ω)
    -the unit used to measure the amount of resistance between two points im a circuit
  28. superconductor
    - a material that has absolutly no resistance to the flow of electric current
  29. Non-Ohmic
    - resistance is not constant so the graph of potential difference against current is not straight
  30. Loads in series
    - loads that are in on the same route which means the current would have to flow through one and then the other
  31. loads in parrallel
    loads that are not in the same route as eachother which would allow them to get the same voltage but not the same amount of current
