Electricity Quiz

Did you know?

• In the late 19th century, Thomas Edison championed the direct current he had developed, against the alternating current promoted by Nikola Tesla and George Westinghouse, which ultimately prevailed.
• Discovered in 1911 by Heike Kamerlingh Onnes, superconductivity allows certain materials to conduct current with zero energy loss once cooled sufficiently.
• Formulated by Gustav Kirchhoff in 1845, his two laws allow complex circuits to be analysed based on the conservation of current and voltage.
• A residual-current circuit breaker compares the current entering and leaving a circuit: any difference signals a leak to earth and triggers an immediate cutoff.
