How fast does the field radiate out
WebWhen there is a difference in charge potential separated by a distance (the negative underside of the cloud located say 1 mile from Earth's surface with a local positive charge) a voltage difference occurs. As charge accumulates in the cloud the total difference in electrical potential (voltage) between the cloud and Earth also increases. WebRadiation may be thought of as energy in motion either at speeds equal to the speed of light in free space—approximately 3 × 10 10 centimetres (186,000 miles) per second—or at speeds less than that of light but …

WebThe critical field increases with decreasing temperature. For the superconducting elements, its values ( H0) at absolute zero range from 1.1 oersted for tungsten to 830 oersteds for tantalum. These remarks about the critical field apply to ordinary (so-called type I) superconductors. WebInitially, the current and radiated field follow the rise in voltage. However, after the voltage peak is reached they begin to fall slightly faster in value and then exhibit a negative …
