Homework Statement
H1=10
H2=-10
B1=1.5
B2=-1.5
Homework Equations
(change)Uloop = (change)H2*B2 + (change)H1*B1
The Attempt at a Solution
=(H1-H2)(B2-B1)
=(10-(-10))(-1.5-1.5)
=-60 j/m^3
So, it sould be someting like ((H1-H2)(B2-B1))*f ?You're on the right track but you have computed the energy dissipated in 1 cycle (but with the wrong units). Now convert the energy per cycle to the time rate of energy dissipation.

Yes. A lot like! :-)So, it should be someting like ((H1-H2)(B2-B1))*f ?
You didn't go wrong. I did. The per-cycle energy dissipation units are J m^{-3} just as you said. Except the final answer is of course in J sec^{-1}m^{-3}.Where did I go wrong with units?
Is it j/m^2 due to area (not volume)?
So, final answer sould be:Yes. A lot like! :-)

OK, except no minus sign. Energy is dissipated in heat.So, final answer sould be:
=((H1-H2)(B2-B1))*f
=-60 * 50
=-3000 j sec^-1 m^-3
Makes sense. Thanx for help :)
