Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
Core type Transformers: in this type of transformer the windings enclose the core (fig .given below). Both the windings are separated and half of every winding is placed on ever
