Predict: Suppose the ecosystem expands allowing the prey access to a much larger grazing area at point C. How would this affect the next cycle of the predator and prey population? *

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
