  • Q8
    Does a thick wire or a thin wire have more resistance? Why?
    The thin wire has more resistance because it can get clogged full of electrons and stop the current
    The thick wire has more resistance because there is more surface area for heating
    The thin wire has more resistance because not as many electrons can fit through it
    The thick wire has more resistance because there is more material

  • Q11
    When the circuit is closed, which statement best describes the brightness of the bulbs?
    Question Image
    A is brighter than B because it experiences more current
    B is brighter than A because it experiences more current
    They are the same brightness because parallel circuits deliver equal voltage to each branch

  • Q12
    When the circuit is closed, which statement best describes the brightness of the bulbs?
    Question Image
    B is brighter than A because it experiences more current
    A is brighter than B because it experiences more current
    They are the same brightness because they each get all 10 volts from the battery

  • Q13
    When the circuit is closed, which statement best describes the brightness of the bulbs?
    Question Image
    A is brightest because it gets all 10 volts from the battery
    B and C are the brightest because they have less resistance
    They are the same brightness because they experience the same current
    B is the brightest because it has low resistance and gets the current before it makes it to C
