AI Thread Summary
In a series resistor circuit, the current remains constant because the total resistance increases, which adjusts the current output from the voltage source according to Ohm's Law. When additional resistors are added in series, the voltage source compensates for the increased resistance by altering the current supplied to the circuit. The concept of conservation of energy is key, as the current, or flow of electrons, must pass through each resistor, resulting in a voltage drop across them. This drop represents the energy lost due to resistance, but does not change the overall current flowing through the circuit. Thus, while resistance opposes current flow, it does not affect the uniformity of current in a series configuration.

resistance is oppsition to the flow of current then why the current is same in series resistive ciruit..??

Any complex circuit can be simplified, this being the case -- what does current see entering a circuit?
 
Remove or add a load and you will see that the current value changes.
 
soft land, if you have a voltage source connected to one resistance, what will happen is that the voltage source will look through it's terminals finds the amount of resistance connected to it and figure out who much current it can give to the circuit by applying ohm's law and then outputs that current. now if you connect two resistances in series the voltage source will again look at it's terminal only this time to find that the resistance have increased thus adjusting the current given to the circuit.

Also another way to look at it is that the current is a given quantity of electrons flowing through the resistance. when the current passes through the resistance or "opposition" it slows down but it must pass -where else would it go- this slow-down is simply the voltage drop across the resistance.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
