thanks pcbelarge , i have another questions,
i have read wattage is electrical power, but then i read its the amount of electrical energy converted to anther form? also, if somthing has a higher wattage, would it always be more powerful then a lower wattage? i say this because if the voltage and resistance are both high, then the ampere will be low, lower then a lower wattage with a higher ampere? i am very confused about this

thanks for any help, scott
