NIKOLA TESLA 1856 - 1943 INVENTOR, ENGINEER & FUTURIST
Nikola Tesla has certainly been an unsung hero of the 19th and 20th Centuries. A native to Serbia which was then part of the Austro-Hungarian Empire, Tesla eventually emigrated to the USA in 1884 where he developed patents, conducted experiments and was involved in the battle of the currents! It's only in the last few years, that he is being recognised as others took credit for his work. Certainly at school we heard of Marconi, Edison etc, but never of Tesla. Perhaps partly his own fault as he was quite an introvert and never saught fame for his own inventions and achievements. Achievements is maybe an understatement, one would call them colossal! To name a few:
- Wardenclyffe Tower (Wireless Power Transmission)
- Tesla coil
- Polyphase System
- X-ray experimentation
One has to wonder where half of his ideas even came from. Nevertheless, he was well ahead of his time and no doubt some of today's problems could be solved by him. Sadly he died in poverty in 1943.
In 1960, 'Tesla' was defined as the unit of measure for the strength of a magnetic field in an electrical circuit.
The type of metal that is attracted to a magnetic field or magnet is a Ferrous metal. "Ferrous" means generally "containing iron (Fe)". The word is derived from the Latin word ferrum ("iron"). Ferrous metals include steel and pig iron (with a carbon content of a few percent) and alloys of iron with other metals (such as stainless steel). Let it be known not all stainless steel types are attracted to magnets.
There are two types of electrical current. AC (alternating current) and DC (direct current). The differences are important. AC has a rotational magentic field, whilst DC is static. With DC though, if you pass a conductor through a static magnetic field, a voltage is induced.
Now Nikola had a small problem to solve to help find a hidden cache, can you help him?
CACHE IS NOT AT POSTED COORDINATES!
The cache can be found at the following co-ordinates:
Take a multitool with flat head piece.
N A° B.C' W D° E.FG'
The questions do not follow any order however, some answers may be linked to further workings.
A = Frequency (F) of the UK electrical system + 5 ?
B = Calculate the reactance (XL) of the Inductor (L) in Ohms? (Round to nearest whole number)
C = Calculate the reactance (XC) of the Capacitor (C) in Ohms? (Round to nearest whole number)
D = Number of phases used in the UK electrical system?
E = 'Fe' - 2
F = Calculate the voltages across each individual component L, C and R. Add these answers together then divide by 67. You will need to know the voltage for a domestic supply to help you. All workings to be rounded off to the nearest whole number.
G = Calculate the total impedance (Z) of the electrical circuit in Ohms? (Round to nearest whole number)
Do you think your household is supplied via AC or DC? Add this to your log is an added bonus!
