For electronic machines like voltage regulators, transistors, and other similar gadgets the expression current rating is more commonly used than ampacity, but the considerations are broadly similar. The tolerance of short-term overcurrent, however, is almost near zero forsemiconductordevices, because the...
Electromagnetic waves are formed by the combination of magnetic and electric fields. The light and the colour that you see are due to the presence of electromagnetic waves. Some of the important examples of electromagnetic waves are: Microwaves, Lightwaves, thermal radiation, X-rays, Radio waves ...
