What are the five types of energy?

Education Journalist | Study Abroad Lead

There are different forms of energy that can be transformed from one to another. Energy can never be created or destroyed, it can only be transformed. The two most basic types of energy are potential energy and kinetic energy.

The energy that is present in things that move is known as kinetic energy.
Examples of kinetic energy include mechanical and electrical energy.
The energy stored in objects that can be used in the future is known as potential energy.
Examples of potential energy include chemical and nuclear energy.

Types of Energy

The five different types of energy are as follows:

Electrical Energy

Electrons are tiny particles that along with protons and neutrons form atoms. The movement of these electrons is known as electrical energy. When the electrons move through a wire, it is known as electricity.

Chemical Energy

The energy that holds atoms and molecules together is known as chemical energy. The energy is stored in the bonds. It is also found in biomass, natural gas, food, and petroleum.

Mechanical Energy

Mechanical energy is the energy stored in different objects. More energy is stored in the objects as they move faster. Examples of mechanical energy include wind, a moving car, or a running person.

Thermal Energy

The energy created from the vibration of atoms and molecules of a substance is known as thermal energy. The faster the atoms move, the more energy they have, and thus the objects become hotter. It is also called heat energy.

Nuclear Energy

The energy stored in the nucleus of atoms is known as nuclear energy. When the nuclei combine through fusion or split apart through fission, nuclear energy is released.

Capacitors are manufactured with certain standard capacitances and working voltages. However, these standard values may not be the ones that are actually needed in a particular application. Two or more capacitors can be grouped in series or in parallel to achieve desired capacitance and voltage. When connected in series, the total capacitance decreases while the voltage rating increases, whereas in parallel connections, the total capacitance increases and maintains the same voltage rating. A capacitor stores energy in the electric field between its plates and stored energy is proportional to the square of the voltage and capacitance $U = \frac{1}{2}CV^2$, where symbols have their usual meanings.
Two capacitors, one of $3 \ \mu$F and the other of $6 \ \mu$F, are connected in series in the circuit as shown in the figure, for a long time. }
