Hi Everyone,
I've just completed a single ez1290 and I've got a smoking resistor. it's the 12 ohm 1 watt r56.
I was wondering if someone could give me a voltage reading across it?
I've got a 10 ohm and 2.2 (both 1 watt) wired in series cause I didn't have a 12 ohm.
From 23.9 volt supply i get a 2 volt drop across the 2.2 ohm and a 9 volt drop across the 10 ohm. These figures seem high to me, and it's apparent why they are smoking:
P= V^2/R = 81/10 = 8 watts. which is much higher than the rated power dissapation.
Could someone give me a reading?
Thanks so much!!
