Electronic Principles The core of an electromagnet is said to be in saturation when: frequent changes in the direction of current through the coil causes heating effects in the core material the core is permitted to move freely within the coil None of these an increase in current through the coil causes no further increase in the mmf changing the polarity of the current in the coil changes the polarity of the magnetic field around the core frequent changes in the direction of current through the coil causes heating effects in the core material the core is permitted to move freely within the coil None of these an increase in current through the coil causes no further increase in the mmf changing the polarity of the current in the coil changes the polarity of the magnetic field around the core ANSWER DOWNLOAD EXAMIANS APP
Electronic Principles What is the difference between a conductor and an insulator? A conductor allows current to flow much easier than an insulator does An insulator has an excessive number of free electrons, while a conductor has a few free electrons or none at all None of these An insulator allows current to flow much easier than a conductor does The difference between conductors and insulators depends on how they are used A conductor allows current to flow much easier than an insulator does An insulator has an excessive number of free electrons, while a conductor has a few free electrons or none at all None of these An insulator allows current to flow much easier than a conductor does The difference between conductors and insulators depends on how they are used ANSWER DOWNLOAD EXAMIANS APP
