What will happen in the diagram if a lightbulb
placed at d and b is closed?

•the lightbulb will be off.
•the lightbulb will be dimmer than
normal.
•the lightbulb will be on.
•the lightbulb will be short circuited.
ingle

Explanation:

There is no other resistance in the circuit.  It is as though B was a wire. The light bulb with show its normal brightness with a voltage of A. So the answer is C

A: the lightbulb will light A is incorrect.

B: is incorrect. It will be as bright as is normal for bulb and battery

D: is incorrect. If the switch were placed across D, then the light bulb would be shorted out.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
