Joule's law
Joule's law (due to James Prescott Joule) expresses the amount of heat generated by an electrical resistor, and is expressed by the relation
- Q is proportional to <math>I^2 R t</math>
by current I flowing through a resistor with resistance R for a time t, and Q is the heat generated
or
- <math>Q = k I^2 R t</math>
where k is the constant of proportionality, dependent on the units used to express I, R and t. If amperes, ohms, and seconds are used, and the result expressed in joules, it is simply 1.
- <math>units = J / A^2 \Omega s</math>
first to recover himself: after thinking a little, he said -
"Your will, dear lady, is law. Next Monday evening, I will bring you
priest who first welcomed me to England. It was but a poor return
through the cholera, of which he died. He left me all that he had--
and rosary, and his papers. How some of those papers came into his
