Current in an inductor can not change instantaneously. If you are going to interrupt the circuit, you should provide a path to allow the inductor current to continue (catch diode in a switching power supply) or diminish (diode across a relay winding), etc. If not, you let Mr. Murphy determine where the energy will go, sometimes with exciting consequences. :-)</div><div id="yui_3_16_0_1_1457562766890_7542" dir="ltr"><br></div><div id="yui_3_16_0_1_1457562766890_8028" dir="ltr">Sincerely,</div><div id="yui_3_16_0_1_1457562766890_8029" dir="ltr">Kevin Schilf<br></div><div id="yui_3_16_0_1_1457562766890_7318"><span></span></div><div id="yui_3_16_0_1_1457562766890_7319" class="qtdSeparateBR"><br><br></div><div style="display: block;" id="yui_3_16_0_1_1457562766890_6997" class="yahoo_quoted"> <div id="yui_3_16_0_1_1457562766890_6996" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1457562766890_6995" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1457562766890_7071" dir="ltr"> <font size="2" face="Arial"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Pete Soper via TriEmbed <triembed@triembed.org><br> <b><span style="font-weight: bold;">To:</span></b> triembed@triembed.org <br> <b><span style="font-weight: bold;">Sent:</span></b> Wednesday, March 9, 2016 5:25 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [TriEmbed] N-MOSFET Symbol<br> </font> </div> <div id="yui_3_16_0_1_1457562766890_6994" class="y_msg_container"><br>I'm pretty sure about 70% of Brian's interest in this subject involves <br clear="none">dealing with inductive loads.
