The correct interpretation of this information is that: if you increase the resistance in a circuit, and you want to maintain the same current, you must do something to increase the voltage applied to the circuit
it is not the case that increasing the resistance in a circuit will increase the voltage.

I have corrected my previous post.If only one resistance in a series circuit containing more than one resistance is increased, the voltage drop across THAT resistance WILL increase. Since the applied voltage remains the same, and the sum of the voltages dropped by each resistor is equal to the applied voltage, the voltage dropped by the other resistors in the circuit must decrease. The current will also decrease due to the increase in total resistance.
This change in voltage is easily demonstrated with a few resistors, a battery and a voltmeter.

Oh, I see what you were getting at. That makes sense. Sorry if I seemed overzealous there.fleet130 wrote:The correct interpretation of this information is that: if you increase the resistance in a circuit, and you want to maintain the same current, you must do something to increase the voltage applied to the circuit
While this is true, I didn't want to increase the applied voltage to maintain the same current. I wanted to show the effect that changing one resistance in a series circuit would have on the circuit.
