@Andy aka if you read the answer a little bit below that statement (which is true) i say we have voltages due to mutual inductance-> we can say that a current exitting the doted end of the inductor can be translated to a voltage drop from the dotted end to the undotted end.

A: Coupling of inductors When 2 inductors share the same magnetic field they become coupled and besides their self inductance they have a mutual inductance as well. For this circuit:  Now current entering one coil marked with a dot, produces a ... (more) |

The circuit isnt wrong but what you have suggested is a improvement of the current source/switch relationship. (more) |

1) The current source provides 0.1A to the circuit but this could well have been a typo or you may have not seen it well which is partly my fault because I didnt write it brightly enough 2)the time costant is L1/R so the t/T must have units of Ohms*seconds/Henries (more) |

| Answer | — |
A: Select resistor for a diode A diode obeys the Shockley diode equation and for this circuit we have:hi hi The current through the diode must not pass a limit so for LTL-307EE we go to the datasheet to find the maximum current before the diode is destroyed: For the LTL-307EE at 20C we have 10^4 A Isat and Vth=0.026V...
