quote:Also sometimes a 1/2 watt resistor is called for so 2, equal 1/4 watt resistors in series gives you a 1/2 watt one for example at 2 times ohm value.
You lost me on this one. It has been a long time since I studied ohms law back in school so bear with me on this as my brain doesn't always function in the right direction. I always thought that regardless of how many resistors were in series they were still only rated for what their rated value was, as 1/4 watt rated resistor stayed 1/4 watt rating. If you put 2 1/4 watt reesistors of the same value in parrallel wouldn't each carry have the load and give you 1/2 watt protection with half the resistance of the reated value of the resistors. Can you show the formula to calculate this.
