D: Heat energy from the sun is transferred to water bodies to warm the water. The result is stored (thermal) energy. The warm water heats the air over it. Warm air rises, so the air is now in motion. The moving air now has kinetic energy. E: Kinetic energy in the moving air is a source of energy called Wind Energy.

Read More8.4: Energy Stored in a Capacitor
The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.
