When I look up the answer to an electronics question online, it's often a physicist who is giving the answer. Do they know more about electronics than someone who actually works with electronics? |

If it's something like Ohms law or other sorts of fundamental stuff, I don't see why they would not. |

Electronics is applied physics. |

What question did you ask them? If it is something along the lines of "What kind of circuit should i use to transfer power and bidirectonal communication simultaneously over 2 wires" or "How do i make the switchmode regulator <Insert part no. here> output be digitally adjustable" you are very unlikely to get any sort of even remotely useful answer out of a physicist. If you instead ask something along the lines of "How does a bipolar transistor work?" or "How does an LED work?" or "Why do resistors make thermal noise?" then you are indeed more likely to get a much better answer out of a physicist. The electronics engineers just simply don't care what the electrons are doing inside of that transistor. They can't poke and touch those electrons in there to make them do anything else than what they normally do. They care about the transistors functionality of amplifying current, so they instead know how the transistor behaves and how to use that behavior to do something useful in a circuit. But physicists are way more interested in those electrons whizzing around inside trough those funky energy levels of the junction, while not really caring about what that transistor could do in a useful circuit. This leads to things like the much debated topic around Dr. Lewin and Kirchhoffs circuit rules. |

Perhaps physicists use electronics more often than electronic engineers use physics? |
