In order to create a spark gap you need an induction\/ spark coil, (also known as an inductorium or Ruhmkorff coil after the inventor, Heinrich Rumhkorff), which produces high voltage pulses from low voltage DC.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003ePlease click on the following link for more \u003ca href=\"https:\/\/mullardantiques.co.uk\/collections\/vintage-technology-scientific-engineering-imaging-medical-equipment-instruments-tools\" target=\"_blank\"\u003evintage technology.\u003c\/a\u003e\u003c\/p\u003e\n\u003cdiv data-element-id=\"id1429604210185\" id=\"id1429604210185\" class=\"design-element element-size-box has-rich-content user-selectable-element clickable-element has-rich-content has-text is-section-child\"\u003e\n\u003cdiv data-element-id=\"id1429604210185\" class=\"element-main-box design-element-main-box has-rich-content user-selectable-element clickable-element has-rich-content has-text\"\u003e\n\u003cdiv data-element-id=\"id1429604210185\" class=\"element-border-box element-border-target element-padding-box design-element-border-box has-rich-content user-selectable-element clickable-element has-rich-content has-text\"\u003e\n\u003cdiv data-element-id=\"id1429604210185\" class=\"element-content-box design-element-content-box has-rich-content user-selectable-element clickable-element has-rich-content has-text\"\u003e\n\u003cdiv data-element-id=\"id1429604210185\" class=\"content-container content-container-type element-size-box element-size-target has-rich-content user-selectable-element clickable-element has-rich-content has-text\"\u003e\n\u003cdiv class=\"rich-text-element-content absolute-fill element-content dir-ltr\"\u003e\n\u003cdiv class=\"rich-text-positioning-wrapper vertical-alignment-top\"\u003e\n\u003cdiv class=\"rich-text-content common-rich-content-style has-content\"\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan class=\"theme-text-color-0-0\"\u003e\u003cu\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/u\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cspan style=\"border-top-left-radius: 2px;
