B. Concept
1. An object is elevated to a location of higher potential
energy (h) with an external source of energy.
2. It is then released from the location where the potential
energy is converted into kinetic energy. The velocity of the
falling object is allowed to accumulate over a period before
its movement is translated into production of electrical
energy3. When the velocity of the falling object has
reached a predefined value, the falling object produces
electricity in two ways, viz by generating armature torque
and by interacting with generating coils. In the process
electrical energy is elicited by kinetic energy of the falling
object.
