Can resistors break

WebSo what we have calculated is that these two resistors connected in parallel can be replaced by a single resistor of eight ohm. And nothing will change. Everything in the circuit will remain the same. The current in the circuit and the voltage, everything will remain the same. So let's go ahead and do that. WebExceeding the allowed environmental temperature range can cause overstressing of wire bonds, thus tearing the connections loose, cracking the semiconductor dies, or causing packaging cracks. Humidity and subsequent high temperature heating may also cause cracking, as may mechanical damage or shock.
