Cross section in electricity

WebAbsorption cross section (ACS) with different antenna stands are measured in a reverberation chamber (RC). The electric-field (E-field) strength is estimated from the measured ACS. Measurement results indicate that the high maximum E-fields generated in a RC is sensitive to the loading object, especially when the unloaded E-field is high. WebJul 25, 2024 · 1. The required wire size is determined by the current it is expected to carry, not by voltage or power. The voltage will determine the required insulation thickness or type. The required wire size for a given current is determined by both resistance heating and voltage drop in the wire resistance. Share.
