Use the drop-down menus to identify the variables for the second hypothesis.
hypothesis #2:
as you build circuits, you will alter resistance, which is the
variable. you will measure how changing
the voltage affects the current, which is the
variable. a "constant" is a parameter that stays the same
regardless of the other variables, and in this case,
is held constant
