Homework Statement I'm new to uncertainty, so I needed a little assistance. The circuit in this experiment was simple, a dry cell connected to a variable resistor. I used an ammeter on the circuit and used a voltmeter across the resistor and took some measurments. The experiment was to...

I tend to worry about the little things! You've been helpful, I'll leave it as infinity. The I/V curve is nonlinear, so I'll have to lookup the calculations for the resistance (Havn't been taught it, yet) and try to apply it to my results!

Sorry I do try to be clear but have a tendency to create the opposite effect :) The criteria I have to obtain is simple itself - I just wanted to ensure that the way I am presenting my results is correct. Using the example data I posted R=\frac{V}{I}=\frac{0.38}{0}=∞ But I know resistance...

New to the forum, I'll say "Hi," first :) Homework Statement Have a physics assignment to hand in. Very simple experiment - increase the voltage in a circuit and measure the current/voltage across the diode in forward and reverse. The problem comes with dealing with infinity in some of the...
