The farad is the SI unit of the capacitance of an electrical system,
that is, its capacity to store electricity. It is a rather large unit
as defined and is more often used as a microfarad.
It is named after the English chemist and physicist Michael Faraday
(1791-1867).

The hertz is the SI unit of the frequency of a periodic phenomenon.
One hertz indicates that 1 cycle of the phenomenon occurs every
second. For most work much higher frequencies are needed such as the
kilohertz [kHz] and megahertz [MHz].
It is named after the German physicist Heinrich Rudolph Hertz
(1857-94).

The joule is the SI unit of work or energy. One joule is the amount of
work done when an applied force of 1 newton moves through a distance
of 1 metre in the direction of the force.It is named after the English
physicist James Prescott Joule (1818-89).

The newton is the SI unit of force. One newton is the force required
to give a mass of 1 kilogram an acceleration of 1 metre per second per
second. It is named after the English mathematician and physicist Sir
Isaac Newton (1642-1727).

The ohm is the SI unit of resistance of an electrical conductor. Its
symbol, is the capital Greek letter 'omega'. It is named after the
German physicist Georg Simon Ohm (1789-1854).

The pascal is the SI unit of pressure. One pascal is the pressure
generated by a force of 1 newton acting on an area of 1 square metre.
It is a rather small unit as defined and is more often used as a
kilopascal [kPa]. It is named after the French mathematician,
physicist and philosopher Blaise Pascal (1623-62).

The volt is the SI unit of electric potential. One volt is the
difference of potential between two points of an electical conductor
when a current of 1 ampere flowing between those points dissipates a
power of 1 watt. It is named after the Italian physicist Count
Alessandro Giuseppe Anastasio Volta (1745-1827).

The watt is used to measure power or the rate of doing work. One watt
is a power of 1 joule per second. It is named after the Scottish
engineer James Watt (1736-1819

More some other time .................... ! There's bound to be a
Russian or two in among those Europeans!
