When activated, the resistance wire coil heats up and vaporizes the liquid, which is then inhaled by the user. [82] The electrical resistance of the coil, the voltage output of the device, the airflow of the atomizer and the efficiency of the wick all affect the vapor coming from the atomizer. [83] They also affect the vapor quantity or volume ...
Vaping [notes 7] generates particulate matter 2.5 μm or less in diameter (PM 2.5), but at notably less concentrations compared to cigarette smoke. [55] Particle concentrations from vaping ranged from 6.6 to 85.0 μg/m 3. [53] Particle-size distributions of particulate matter from vaping differ across studies. [1]
An electronic cigarette (e-cigarette), or vape, [note 1] [1] is a device that simulates smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. [2] As such, using an e-cigarette is often called "vaping". [3]
A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable. The output of the coil, v(t), is connected to a lossy integrator circuit to obtain a voltage V out (t) that is proportional to I(t).

1994–1996 Ford Aspire three-door 1997 Ford Aspire three-door. The Ford Aspire was sold in North America from 1994 until 1997. It was the replacement for the Ford Festiva. It was the first car in its class to have dual airbags standard and anti-lock brakes optional. It came in two and four door body styles, both hatchbacks.
The hatchback model matched the sedan in all other dimensions and offered 38.1 cubic feet (1.08 m 3) of cargo space with its seat folded. [19] By 1972, Ford redesigned the hatch itself, with the glass portion of the hatch enlarged to almost the entire size of the hatch itself, ultimately to be supplemented for 1977–1980 with an optional rear ...
Therapeutic vapes with a nicotine concentration of 20 mg/mL or less are available from a pharmacy to anyone 18 years or older subject to a pharmacists approval. Therapeutic vapes with a nicotine concentration greater than 20 mg/mL or for anyone under 18 require a prescription. [168] Australia is developing regulations on e-cigarettes. [169]
