Re: resistance---series or parallel?

What do you think? What does series mean?

Re: resistance---series or parallel?

sir, i want to know whether the resistances are connected in series or parallel.? i want to find the effective resistance . if they are in series the formula is r1+r2, according to the diagram. if they are parallel means r1r2/(r1+r2). please help

Re: resistance---series or parallel?

sir,
thanks for the link. but i want to know the type of circuit of my diagram, whether it is parallel or series because they are connected across the battery.

Re: resistance---series or parallel?

Sir, i want to find the effective resistance of this circuit. R1 is 5 ohm and r2 is 6 ohm. How to proceed?

Re: resistance---series or parallel?

according to my attachment, how to calculate the effective resistance? i dont know whether my attachment is parallel circuit or series circuit. my attachment does not match with your link, sir

Re: resistance---series or parallel?

two resistances are in series if:

one of the wires of the first resistance is connected to one of the wires of the second resistance.

AND

nothing else is connected to these 2 connected wires.

2 resistances are parallel if:

one wire from the first resistance is connected to the other resistance and
the other wire from the first resistance is connected to the other wire of the second
resistance.

Re: resistance---series or parallel?

thanks mr. william. what about my attachment. are they parallel or series? please...

Re: resistance---series or parallel?

The link I gave in post #7 has an example that matches your attachment almost exactly. (Note that wires can be stretched or bent as you like to make your diagram easier to interpret.)

Rather than keep asking us to tell you the answer, why don't you tell us what you think based on your understanding of what parallel and series means.

thanks. they are connected in series. am I right, sir?
