Study the image of a circuit.
if all the light bulbs are identical, which choice most accurately compares the current moving through a to the current moving through b?
the amount of current moving through a is the same as the amount of current moving through b because all the current moves through all the bulbs in this circuit. the current is the same throughout the circuit.
the current moving through a is greater than the current moving through b because the resistance of the circuit increases as you go through each bulb. going through one bulb has less resistance than going through two bulbs.
the current moving through a is greater than the current moving through b because the current gets to a first. some of the current gets used up by the first and second bulbs, so less current gets to b.
the current moving through a is less than the current moving through b because the current increases as it goes through a bulb. each bulb adds more current to the circuit.
so much.
