las sillas voladoras de la figura tienen las siguientes dimensiones. La longitud L=12m y la distancia "a" 4m. ¿Cual tendria que ser la velocidad tangencial de la silla para que la cuerda forme un angulo de 30º con la vertical? (la silla gira en un circulo horizontal)

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
