Which is a characteristic of centripetal acceleration? it is directed outward from the center of a circle. it is directed inward, toward the center of a circle. it results in an object moving faster. it results in an object moving slower.

It is directed inward toward the center of a circle. Straight from edgenuity

Answer choices? if there is any

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
