when resistance (ohms) is increased, what decreases? i mean is it volts, amps, or any thing else?!

i seem dumb, but believe me, all i know and understand from my textbook are against the ohm law, that is why i am asking this just to be sure....

do you mean the equation of V = IR ? If so, then the volts increase and amps decrease.

so, increasing resistance increases volts? and decreases amps?! what is up with this textbook?!!!

I suppose so, the equation itself says so..

ok, i just saw a website claiming you could decrease voltage with resistors... i am lost now......

wow, to be honest, I don't know, but if we're talking about p.d instead of emf, the voltage might decrease, if you increase the internal resistor, the p.d would decrease as there are loss volts...

i am talking about like a ceramic-carbon (is that what is it called) or like the resistance of a loooong wire....

the only thing I know about long wire is it has greater resistance than shorter wire....

ok, wait V=IR, V for voltage, I for amperes, and R for resistance?! if so, increasing resistance will decrease amperes, then how would volts increase?!

it's to show the relation between each element I think... resistors you use doesn't change though, I and V are the variables that usually change...

You asked: "V for voltage, I for amperes, and R for resistance?! if so, increasing resistance will decrease amperes, then how would volts increase?!" It depends on the context.|dw:1410567302170:dw| Look at the drawing. The voltage 10 volts supplied by the battery will be assumed to be a constant. The total resistance is 8 + 2 or 10 Ohms. The current flow will be 1 amp (Ohm's law) The voltage drop across the 8 ohm will be IR or 8 volts, the 2 Ohm will have the same 1 amp of current giving it a voltage drop of 2 volts. Before we increase a resistor, do you understand those conditions??
