Taral 3 years ago I got a question... Resistor drops or opposes the flow of current but we say 2A passing through resistor and we get 2A What is actual difference???

The current can't disappear in the resistor but it's level is determined by the resistor value, so with a fixed voltage source, the greater the resistor you apply the lower the current you obtain

I can just add an obvious thing: resistor is a component "governed" by Ohm's law. So nick67 is right in this. About the 2 Amps: 2A flow or pass through the resistor (a passive component). We usually get current from a source (an active component).

Got this Guys.. Thank You very much ... and if I got more questions I love to ask... Thanks

Voltage drops across the resistor.Resistor opposes current flow and as the current flow is directly proportional to the voltage applied according to ohms law, voltage reduces then current will also reduce as V=IR and R is constant.

voltage drops across resistance so we can say ohm's low v=IR
