Do you pay attention to the power rating of a resistor?
Probably for most simple circuits, the power rating of a resistor is sufficient to not get damaged. But when the power through the circuit might be a little higher, forgetting or wrongly estimate the power rating can have hazardous consequences. It is not always easy to correctly determine the power rating or not over specify a resistor. How can you make sure you are on the safe side without specifying a too big resistor?
