Ch 8: 4.29.19 Daily Quiz material Flashcards
the flow of electric charge over time
current
electrical potential energy per unit charge
in common parlance, “voltage”
electric potential
the flow of electrons
electricity
equation: current
current (I) is charge (q) over time (t)
units:
C/s (coulomb per second)
1 C/s = 1 A (amp)
what can be thought of as the “push” electroncs feel to move?
electric potential
note: similiar to the relationship between water pressure and the movement of water
equation: Ohm’s law
electric potential (E, in volts [v]) is current (I, in amps [A]) times resistance (R, in ohms, [Ω])
the continuous flow of electrons
curent electricity
examples: lights (once turned on); essentially anything that runs on electricity
opposition to electric flow
resistance
“one jump” of electrons
static electricity
example: lightning
