Elaine drew an electric circuit diagram that includes a door buzzer. but the current in the circuit is too high based on the parts she chose. which part can elaine add to lower the flow of current without changing the operation of the circuit?

a lightbulb

a motor

a resistor

a second battery

The correct answer is a resistor.

Explanation:

The resistor is defined as an electrical device which opposes the flow of current in the closed electric circuit. Addition of resistor in a close electric circuit decreases the flow of current in the circuit.

A light bulb is a source which produces light..

A motor converts electrical energy into mechanical energy

A battery increase the voltage in the circuit.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
