Acircuit consists of one 330 ohm resistor in series with two other resistors (470 ohms and 220 ohms) connected in parallel. what is the power drain on an ideal battery with a voltage of 2.9 v connected to this combination?

power drain on an ideal battery, P = 0.017 W

Given:

Since, and are in parallel and this combination is in series with , so,

Equivalent resistance of the circuit is given by:

power drain on an ideal battery, P =

                                                      P =

                                                      P = 0.017 W

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.
