Gw mau tau Karakteristik nonidéal dari Résistor. Jelasin dalam bahasa sunda

A resistor has a maximum working voltage and current above which the resistance may change (drastically, in some cases) or the resistor may be physically damaged (overhéat or burn up, for instance). Although some resistors have specified voltage and current ratings, most are rated with a maximum power which is determined by the physical size.  Common power ratings for carbon composition and metal-film resistors are 1/8 watt, ¼ watt, and ½ watt.  Metal-film and carbon film resistors are more stable than carbon resistors against temperature changes and age.  Larger resistors are able to dissipate more héat because of their larger surface aréa.  Wire-wound and resistors embedded in sand (ceramic) are used when a high power rating is required.

Furthermore, all réal resistors also introduce some inductance and a small amount of capacitance, which change the dynamic behavior of the resistor from the idéal.
