Measured in ohms (\u03a9), resistors play a critical role in ensuring circuit stability, energy efficiency, and safety.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Engineers, designers, and procurement specialists rely on resistors for applications ranging from <strong>consumer electronics<\/strong> to <strong>industrial automation, networking equipment, and automotive systems<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" ><strong>2&#xfe0f;&#x20e3; <\/strong>How Do Resistors Work?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Resistors operate on <strong>Ohm\u2019s Law (V = I \u00d7 R)<\/strong>, which describes the relationship between voltage (V), current (I), and resistance (R).
