Procedures: 1  Place the chicken stock into a medium saucepan over medium high heat. Reduce the chicken stock by half. 2  Add the shallot to the chicken stock and cook until the shallot is soft and golden. Continue to reduce the stock for a few more minutes. Add in the thyme leaves and the currants, coating the currants with the chicken stock. Add in the honey and vinegar. Simmer the sauce over low heat for about 7 to 10 minutes, or until the black currants have softened and extruded their juices.
Definition of Hydroelectric Energy. Hydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed. Kinetic energy is the energy of motion.
Electric potential is actually defined as the NEGATIVE potential function of electric field (not the vector calculus potential function, but its negative), as is any concept of potential in physics, in order that we can think of it as a form of energy. This means that electric field is the negative gradient of electric potential. If you've never heard of the term gradient, all it means is a vector of derivatives of a scalar function of space, each component of which is a derivative of this function relative to the respective direction in the coordinate system.
