Electric Shock

The human body can conduct electricity and is susceptible to electrical shock. Electrical shock can range from mild tingling to severe burns and even death. The high voltage is not normally fatal as demonstrated by coming into accidental contact with the spark plug lead of a motor car.

Resonant Circuits

An important element of any radio communications equipment is the LC circuit. L is the inductance measured in Henries (H) and named after Joseph Henry (1797–1878). The symbol L for inductance was chosen to honour Heinrich Lenz (1804-1865) who pioneered work in electromagnetic induction.

Ohm's Law

In 1827 a German physicist, Georg Ohm, published a paper on his electrical experiments. The result is Ohm’s Law and the identification of electrical resistance that bears his name.

Diodes

When electricity was discovered, the initial belief was that current flowed from the positive terminal to the negative terminal.
