1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are supposed to resist current. What the heck ...

For each pair of results calculate the resistance, R using \(R = \frac{V}{I}\). Record your results in the third column of the table. Plot a graph of voltage, V on the y-axis v current, I, on the ...

If the temperature of a metal conductor increases, the ions of the metal vibrate more vigorously. Hence, for a metal, resistance increases with increasing temperature. Often the increase in ...
