eV to Wh

electronvolt

• Definition: An electronvolt (eV) is a unit of energy that is commonly used in the field of physics. It is defined as the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.

• Symbol: The symbol for electronvolt is eV.

• Usage: Electronvolts are primarily used to express the energy levels of subatomic particles, such as electrons, and in the context of atomic and nuclear physics. They provide a convenient way to measure very small amounts of energy that are relevant in these fields.

watt hour

• Definition: A watt hour (Wh) is a unit of energy equivalent to one watt of power used for one hour. It is a measure of electrical energy.

• Symbol: The symbol for watt hour is Wh.

• Usage: Watt hours are commonly used to quantify energy consumption in electrical appliances and to measure the capacity of batteries. It helps consumers understand how much energy devices consume over time.

Origin of the electronvolt

• The origin of the electronvolt can be traced back to the early 20th century when physicists were exploring atomic and subatomic processes. The term was introduced to provide a simple way to express the energy changes in particles, particularly in the context of experiments involving electric fields.

Origin of the watt hour

• The watt hour originated from the need to quantify electrical energy consumption. The watt, a measure of power, was defined in the late 19th century, and the watt hour developed as a convenient unit to express the total energy used over time. Its use became widespread with the advent of electrical utilities and the increasing consumption of electrical power.
