Thisconstant, now designated as Joules equivalent, is the principal experimental datum of the science of thermodynamics.
The coefficients, P and P', are called coefficients of the Peltier effect, and may be stated in calories or joules per ampere-second.
Measure is equivalent to 4.177 joules per calorie at 16.5° C., on the scale of Joule's mercury thermometer.
10° 15° 20° 2 5° 3 O ° 35° Joules Per Cal.
By Ohm'S Law, And By The Definition Of Difference Of Electric Pressure Or Potential, We Obtain The Following Alternative Expressions For The Quantity Of Heat H In Joules Generated In A Time T Seconds By A Current Of C Amperes Flowing In A Wire Of Resistance R Ohms, The Difference Of Potential Between The Ends Of The Wire Being E = Cr Volts: H=Ect=Crt=E Z T/R.
