Hi ,
I have a doubt related to Resistor power rating , How much it is important to consider the power rating for an Resistor ?
Generally people saying that the power rating for a Resistor should be greater than the power dissipates
through it . Is it a serious thing to consider practically when we are designing a ckt.
Ex.
If is the case that a simple ckt has a supply of 24v and 2A then the power dissipates across the resistor is 48w , so Is it necessary to consider 48W power rating resistor ?
