The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).
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 ...
