Can airplanes trigger lightning?

Aircraft often trigger lightning when flying through a heavily charged region of a cloud. In these instances, the lightning flash originates at the airplane and extends away in opposite directions. The Federal Aviation Administration estimates that commercial jet airliners in the US are struck by lightning once every 1,000 flight hours, or once each year, on average. Planes can even trigger lightning themselves by flying through ionized clouds

The good news is that modern-day airplanes are designed to minimize the impact of suck strikes, protecting both the aircraft and its passengers. When a bolt of lightning strikes the exterior of an airplane, the electricity travels into the aluminum shell and out through another point on the aluminum. For safety reasons, planes hit by lightning mid-flight undergo inspection after landing but in most cases, the aircraft is either unharmed or sustains only minor damage. Lightning typically strikes a relatively sharp edge of a plane, like a wingtip or nose, and the current exits via the tail.

Lightning doesn't pose any serious danger to flights, you would have heard more about it by now. Much like you're safe in a car that gets hit by a bolt, provided you're not touching its metal frame, airline passengers are safe from in-flight lightning strikes.

Evolution of Aircrafts

Since that fateful day in December of 1903, airplane design has changed dramatically. The Wright Brothers built a biplane with two propellers that were chain-driven by a gasoline motor. Our dependence on air travel over the years has forced airplane design to catch up with the times. On December 17, 1903, Wilbur and Orville Wright made four brief flights at Kitty Hawk with their first powered aircraft. The Wright brothers had invented the first successful airplane. The Wrights used this stopwatch to time the Kitty Hawk flights. Aircrafts have evolved so much from the initial days. From 2 seater to the latest air bus type, they have come a long way.  The history of aviation extends for more than two thousand years, from the earliest forms of aviation such as kites and attempts at tower jumping to supersonic and hyper-sonic flight by powered, heavier-than-air jets. Kite flying in China dates back to several hundred years BC and slowly spread around the world. Sir George Cayley...

How Electric Current is formed?

How Electric Current is formed? Have you ever wondered how Electric Current is formed? Generally, the flow from one point to another through a medium is called a current. When an electric charge moves from one point to another inside a conductor or a semiconductor, it is actually conducting electric current. Electric charge carriers are micro particles that conduct the electricity. They can be protons, electrons, holes or ions depending on their availability in the conducting material.  Normally electrons and holes are responsible for conducting electricity. This process occurs when a Voltage or a Potential Difference is applied at the two ends of a conductor or a semiconductor. Thus Electric Current is formed when a Voltage of Potential Difference is applied at the two ends of a conductor or semiconductor, i.e. when a closed circuit is formed.
