# Current in Series

1. Feb 6, 2016

hey, sir i have a question why the current remain same in series combination of resistance?

### QuantumQuest

As you apply a voltage to the two resistors in series, electric current path is through the first and then the second resistor and then back to the voltage source. So effectively, according to Ohm's law: I = V/(R1 + R2) and the total current flowing in the circuit, is given by previous relation.So, it is the same for both of resistors.

Your question is not stated correctly. "remain same" compared to what?

sorry sir

5. Feb 6, 2016

thanks sir what about voltage in parallel?

Now, you can figure out this your own, using a similar logic to the first question: what is changing and what remains constant regarding each resistor?

in series voltage change but current constant

voltage

That's VERY hard to do since your statements and questions are completely unclear. Draw a circuit diagram of a circuit that confuses you and let's talk about it.

my question is
why voltage remain constant in parallel circuit?

What is your understanding of voltage?

13. Feb 7, 2016

work done to bring charge

14. Feb 7, 2016

or it is the energy that provide source to move charge

Those are vague definitions. How do you measure voltage experimentally?

### cnh1995

What I want to emphasize is the nature of current and voltage. Current flows "through" a component and voltage is developed "across" a component. Now can you answer your own question?

By connecting a voltmeter parallel with circuit

littlle bit confusion
