So according to ohm's law circle,
resistance is equal to

The current that flows through most substances is directly proportional to the voltage V applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: I∝V I ∝ V .

your answers are a,b,,e and f

i hope this

the dependant variable is spilled water

the independent is the heat
