9.0 volts = 9.0 Joules/Coulomb
9 J/C * 20 C =180 Joules

Electro is incorrect - the device is non linear, and the resistance will enhance with the sq. of the present. I calculate the present to be a million.40 six Amperes. examine: a million,40 six * 3.a million = 4.fifty 3 volts around the three.a million Ohm resistor a million.40 six * 3.9 = 5,sixty 9 volts around the linear area of the thermistor a million.40 six^2 * a million.4 = 2.ninety 8 volts around the non-linear area of the thermistor Sum of voltages = 13,2 that's the batttery voltage

You need to provide a discharge rate, or a mAh rating.
