hello
i am making a small circuit composed of 4 AA rechargeable batteries in a box with an on/off switch and one red and one black wire
can you please suggest a type/spec of resistor to put into this circuit that will generate heat above 40c and below 70c
thanks in advance for any suggestions/explanations
