{"product_id":"investigating-resistivity","title":"Investigating Resistivity","description":"\u003cp\u003eLow cost apparatus for student investigation into resistance, length and cross-sectional area\u003c\/p\u003e\r\n\u003cp\u003eAlso acts as a bridge or potentiometer.\u003c\/p\u003e\r\n\u003cp\u003eThis 40cm Resistance Board is designed to allow students to investigate resistance quantitively. The board is fitted with 4mm terminals connected by a length of resistance wire against a scale, and a “jockey”.\u003c\/p\u003e\r\n\u003cp\u003eWire samples are provided. These are 0.30mm, 0.44mm and 0.54mm in diameter. Experiments into the relationship between resistance and cross-sectional area can easily be conducted. If required other types of material can be connected between the sockets and their resistance investigated.\u003c\/p\u003e\r\n\u003cp\u003eSockets are provided to enable the board to be used as a 40cm bridge\/potentiometer. The Unilab Basic Student Meter (B8H30981) fitted with appropriate shunt is ideal for use with this board. Power can be provided by a 1.5V SP2 (R20) battery and or any low voltage power supply (e.g. Lockmaster B8G85469).\u003c\/p\u003e\r\n","brand":"Philip Harris","offers":[{"title":"Default Title","offer_id":51272734736667,"sku":"HC1008349","price":109.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0915\/4363\/4203\/files\/HC1008349.jpg?v=1769447750","url":"https:\/\/abcschoolsupplies.ie\/products\/investigating-resistivity","provider":"ABC School Supplies ","version":"1.0","type":"link"}
