If the electric circuit is purely resistive, that is, a configuration of resistors only connected to a battery; the source energy continually gets dissipated entirely in the form of heat. This is known as the heating effect of electric current.
convection current. The heating and cooling of the ï¬uid, changes in the ï¬uidâs density, and the force of gravity combine to set convection currents in motion. Convection currents continue as long as heat is added to the ï¬uid. Convection currents ï¬ow in the mantle. The heat source for these currents is heat from Earthâs core and from the mantle itself. Hot columns of mantle material rise slowly.
