inside an adiabatic cylinder fitted with a frictionless piston and containing an
ideal gas. A current

Solution: Click For PDF Version Resistance of the coil is
If the temperature of the gas inside the cylinder has to remain unchanged, the piston will move up with speed such that the gravitational potential energy of the piston equals P. That is We thus find the speed with which the piston will be moving up to be |
