the first law of thermodyanamics states that energy cannot be created or destroyed in an isolated system described the transfer of energy involved in a tidal power generated system from its source to its electrical output stating the type of energy involved at each stage

Solution

The gravitational forces of sun and moon causes the tides in the oceans. At the high tide region we placed the turbines the wheel of turbine capture the kinetic energy of the tides and convert it into mechanical energy by rotation of turbine and it combines with the generator shaft, then the mechanical energy converted into electrical energy through a generating system.

Thus we have three stages

Kinetic energy

Mechanical energy

Atlast electrical energy stage we get output
