Basic electricity

Dear All,

I have a very basic doubt in electricity.

Consider three resistors 1K,2K and 4K in series with the supply of say 'V' volts.

Now since resistance is the opposition to the flow of the current, the 2K resistor should oppose the current more than the 1K resistor and so must the 4K resistor.

So how come that the current in a series circuit is same ?

as the rate of flow of electrons throught the resistors will vary.

In a series circuit yes becuase the three resistors are acting like one big 7K resistor. But put them in parallel with 'V' and watch what happens.

Measure the voltage drop across the three resistors and you will see the difference.
