are there different types of lightning?

Different Types of Lightning. ... There are three primary types of lightning which include: cloud-to-ground (the most commonly known type), cloud-to-air, and cloud-to-cloud. With cloud-to-ground lightning, the rapid discharge of lightning is a channel of negative charge that is attracted to the positively charged ground.

['There are four popular types of lightbulbs: incandescent, compact fluorescent (CFL), halogen, and light-emitting diode (LED). ... ', 'Incandescent: These are the most commonly used type of bulb and are usually the least expensive.']

The width of a thumb and hotter than the sun While the intensity of a lightning strike can make them appear as thick bolts across the sky, the actual width of a lightning bolt is only about 2-3 cm. The average length of a lightning bolt is about 2-3 miles.

Cloud-to-ground lightning bolts are a common phenomenon—about 100 strike Earth's surface every single second—yet their power is extraordinary. Each bolt can contain up to one billion volts of electricity.

Types of earthquakes. There are many different types of earthquakes: tectonic, volcanic, and explosion. The type of earthquake depends on the region where it occurs and the geological make-up of that region. The most common are tectonic earthquakes.

There are actually five main types of fires. Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach.

An average bolt of lightning, striking from cloud to ground, contains roughly one billion (1,000,000,000) joules of energy. ... In the forms of electricity, light, heat and thunder, this energy is all released by the flash in a matter of milli- or even microseconds.

Unlike power circuits, lighting circuits are always of the radial type: the cable leaves the consumer unit and runs to each outlet position before terminating at the last fitting on the line. Most houses have at least two lighting circuits - usually one upstairs and one down.

Less than 5 to 10 percent of lightning strikes are positive. The rest are negative. ... Positive lightning carries a much greater charge and a longer flash duration than negative lightning, reaching up to 1 billion volts and 300,000 amps, compared with 300 million volts and 30,000 amps with negative lightning.

Cloud-to-ground lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts. Objects on the ground generally have a positive charge under a typical thunderstorm.

Forked lightning is quite visible as in the image above. ... Sheet lightning is a bolt that you can't see because it is hidden by the cloud that it lights up. Most often, it is cloud to cloud or in-cloud (from one part of a cloud to another part of the same cloud.) Lightning can strike “out of the blue” on a clear day.

The Type 1 SPD is recommended in the specific case of service-sector and industrial buildings, protected by a lightning protection system or a meshed cage. It protects electrical installations against direct lightning strokes. ... Type 1 SPD is characterized by a 10/350 µs current wave.

Is Lightning Alternating Current (AC) or Direct Current (DC)? Lightning is transient impulse. Its neither AC nor DC but a composition of AC and DC.

The Eiffel tower and lightning have a long history. Since its birth in 1889, the monument has "attracted" lightning during storms – there are on average 5 impacts every year. And yet, this doesn't affect it, and it doesn't pose any risk to the public either.

The four types of fire detectors are heat, ionization, photoelectric, and ionization/photoelectric. The differences in each of these how they detect fires, heat being from temperature, and the other three being from smoke.

There are four main types of injuries: electrocution (fatal), electric shock, burns, and falls. These injuries can happen in various ways: Direct contact with exposed energized conductors or circuit parts.

As it turns out, not all smoke alarms are the same. There are two basic types of detectors: ionization and photoelectric. Ionization models are quicker to spot flaming fires.
