{"product_id":"capax-capacitive-reactance-pixel-sticker","title":"Capax – Capacitive Reactance Physics Sticker","description":"\u003cp\u003eMeet Capax, a capacitor who blocks steady current but lets fast wiggles through. Capacitive reactance is 1\/(2πfC): a 1.0 μF capacitor gives about 3200 Ω at 50 Hz but only 32 Ω at 5000 Hz. At zero frequency it is infinite, which is how tweeters block bass. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658602909799,"sku":"12969396226104239148","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658602942567,"sku":"21685282456140992027","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658602975335,"sku":"25191115383974500188","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658603008103,"sku":"74319203444936046675","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_6c7e1390-17ec-4e03-bfdb-8140a0f031fa.jpg?v=1792803619","url":"https:\/\/pixelatedphysics.com\/products\/capax-capacitive-reactance-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
