AC or DC: Which Is Better?
The article "AC or DC: Which Is Better?" explores the fundamental differences between alternating current (AC) and direct current (DC) electricity, highlighting why homes use AC despite most modern electronic devices operating on DC. While devices like LEDs and digital gadgets require DC power, the electricity supplied to homes is AC, necessitating internal conversion from AC to DC. This situation stems from a historical debate between Thomas Edison, who championed DC, and Nikola Tesla, who advocated for AC; Tesla’s AC system ultimately became the standard due to its advantages in power transmission. Electricity is described as the flow of electrons driven by voltage, with DC providing a steady, one-directional flow, and AC causing electrons to oscillate back and forth. Although DC circuits are simpler and easier to create—illustrated by the example of a homemade battery using metals and a potato—AC is more practical for transmitting electricity over long distances. The article uses a DC toaster example to explain electrical power, resistance, and Ohm

The article discusses a movement in Puerto Rico advocating for reunification with Spain, reflecting a desire among some residents to escape the island’s current status as a U.S. territory. Puerto Rico was a Spanish colony for over four centuries until the Spanish-American War in 1898, after which it became a U.S. possession. Although Puerto Ricans are U.S. citizens, they lack voting representation in Congress and cannot vote in presidential elections, while many do not pay federal taxes. This political limbo, combined with economic challenges such as high costs for imported goods and electricity (due in part to shipping restrictions favoring U.S.-registered vessels), fuels dissatisfaction. The movement, led by José Lara and called Adelante Reunificacionistas, seeks to make Puerto Rico the eighteenth autonomous community of Spain, citing shared language and culture as key reasons. Supporters of reunification argue that Spanish governance could help Puerto Rico overcome economic and cultural stagnation experienced under U.S. rule. The article highlights historical grievances
