Exploring the Wonders of Electricity

Electricity is the flow of electrons through a conductor. It's a secondary energy source, meaning it's derived from the conversion of primary sources like coal, natural gas, or solar energy.

There are two types of electric current: direct current (DC) and alternating current (AC). Edison championed DC, while Tesla and Westinghouse promoted AC, which eventually became the standard for power distribution.

Materials vary in their ability to conduct electricity. Silver is the best conductor, offering greater conductivity than copper, but due to cost, copper is commonly used in household wiring and electronics.

Not just renewables and fossil fuels, electricity can be harnessed from unusual sources. For instance, scientists are exploring how to generate power from jellyfish, using their natural luminescence.

Superconductors carry electricity without resistance, thus without energy loss. They function at very low temperatures, and researchers are seeking materials that can achieve this at higher temperatures.

The concept of wireless power was introduced by Tesla over a century ago. Today, we're slowly adopting this through technologies like Qi wireless charging, albeit over short distances.

Electric eels generate electricity using specialized cells called electrocytes. Astonishingly, they can produce shocks up to 600 volts for hunting and self-defense.
