We will use a Spice directive to add a K-Statement (“K Lp Ls 1 “) to this circuit. Linear Technology Corporation provides a widely used, free graphical SPICE simulator known as LTSpice. These models and symbols are made in a way so that the symbol doesn't show the power and ground pins, but they are there. I was speaking with a former coworker, engineer, and friend of mine as I was trying to help him figure out how to do some things in LTspice that he only knew how to do in Pspice, when he said something along the lines of, "you know, the thing that bugs me the most is that there's no way to change your keyboard shortcuts in LTspice." 部品の移動は、”Move”アイコンで行います。 (Move Icon – 移動) 移動したい部品を左クリックします。 (移動する部品をクリック) 移動モードになりますので、移動先の場所で左クリックして配置場所を確定します。 (部品移動のモード) 移動モードからは、右クリックか”Esc”キーで抜ける事ができます。 It has no further meaning beyond that.
