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 ...

Watts are units of electric power. Think of wattage as electricity ... There are many laws in physics, science and nature, ...

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 ...
