Electrical resistivity is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that
Lightning is an example of plasma present at Earth's surface. Typically, lightning discharges 30,000 A at up to 100 MV, and emits light, radio waves, and X-rays. Plasma temperatures in lightning might approach 30,000 K (29,700 °C; 53,500 °F), and electron densities may exceed 1024 m−3.
