Electronic Principles The core of an electromagnet is said to be in saturation when: 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 None of these the core is permitted to move freely within the coil 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 None of these the core is permitted to move freely within the coil an increase in current through the coil causes no further increase in the mmf ANSWER DOWNLOAD EXAMIANS APP
Electronic Principles What is the difference between a conductor and an insulator? The difference between conductors and insulators depends on how they are used None of these 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 An insulator allows current to flow much easier than a conductor does The difference between conductors and insulators depends on how they are used None of these 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 An insulator allows current to flow much easier than a conductor does ANSWER DOWNLOAD EXAMIANS APP
