Oct 16, 2015 at 2:58. Resistors are hard to damage by voltage/current alone - if the stress is short enough (millisecons), you can apply hundreds of Volts (and tens of Amperes) on your 10 Ohms / 20 W resistor without any issues. If you keep the resistor under such stress, it will overheat and eventually burn out.
