How does the electron of the first atom oscillate?
The electron of first atom start to oscillate. As the electron is accelerated from zero to some speed, It generate an electromagnetic wave of same frequency. As speed of electromagnetic wave is equal to speed of light , so within a fraction of second it travel through all the wire and energize each and every atom of t.
What is the proportionality constant of a wire?
Here comes a proportionality constant called resistivity which only depends on temperature and the nature of material. So if the length of a wire is increased 2 times then its resistance also increases 2 times but its resistivity remains constant as the temperature is constant and the material is same.
What is current in physics?
Current is the rate that charges flow through a wire. Since we have an equation for the current as a function of time, it represents the instantaneous current. You can easily calculate the current at any moment in time (as many others have already answered).
How does an electron generate an electromagnetic wave?
As the electron is accelerated from zero to some speed, It generate an electromagnetic wave of same frequency. As speed of electromagnetic wave is equal to speed of light, so within a fraction of second it travel through all the wire and energize each and every atom of the wire equally. So current is same at every point.
What is the resistance of an electrical conductor?
The conductor/wire has an internal resistance which opposes the flow of electrical charges. The “electric current” has a speed (voltage) and a volume (current/amps). While the volume remains constant, the speed (voltage) drops along the wire, thus diminishing the overall “electric current” (power) along the wire.
What is the difference between electric current and voltage?
The “electric current” has a speed (voltage) and a volume (current/amps). While the volume remains constant, the speed (voltage) drops along the wire , thus diminishing the overall “electric current” (power) along the wire. The longer the wire is, the weaker the electrical current gets (f. Continue Reading.
