resistor is a passive electrical component with a nominal resistance of 10,000 ohms (10k\u03a9). In modern circuit design, it is one of the most ubiquitous values found on breadboards and production PCBs alike. Engineers and hobbyists turn to 10k resistors because they hit an ideal electrical middle ground: they limit current to safe, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":23472,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_seopress_titles_title":"","_seopress_titles_desc":"Learn what a 10k resistor is, how to identify its color code, where it is used, and when 10k\u03a9 is\u2014or is not\u2014the right choice for your circuit.","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","_seopress_news_disabled":"","_seopress_video_disabled":"","_seopress_video":[],"_seopress_pro_schemas_manual":[],"_seopress_pro_rich_snippets_disable_all":"","_seopress_pro_rich_snippets_disable":[],"_seopress_pro_schemas":[],"footnotes":""},"categories":[2],"tags":[],"class_list":["post-23470","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-pcb-design"],"acf":[],"meta_box":[],"_links":{"self":[{"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/posts\/23470","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/comments?post=23470"}],"version-history":[{"count":0,"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/posts\/23470\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/media\/23472"}],"wp:attachment":[{"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/media?parent=23470"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/categories?post=23470"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lead-pcb.com\/ko\/wp-json\/wp\/v2\/tags?post=23470"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
