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 Energy. Potential energy can be defined as the capacity for doing work which arises from position or configuration. In the electrical case, a charge will exert a force on any other charge and potential energy arises from any collection of charges. For example, if a positive charge Q is fixed at some point in space, any other positive charge which is brought close to it will experience a repulsive force and will therefore have potential energy.
