Resistors | Ohm''s Law | Electronics Textbook
Resistors are rated both in terms of their resistance (ohms) and their ability to dissipate heat energy (watts). Resistor resistance ratings cannot be determined from the physical size of the resistor(s) in question, although approximate power ratings can. The larger the resistor is, the more power it can safely dissipate without suffering damage.
