Current<\/p>\n<p>A parallel circuit resonance is a phenomenon that occurs when the inductive and capacitive reactances of a parallel circuit are equal in magnitude and opposite in sign. This causes the current to flow through the circuit to be amplified.<\/p>\n<p>The inductive reactance of a circuit is given by the following equation:<\/p>\n<p>$X_L = 2\\pi f L$<\/p>\n<p>where $f$ is the frequency of the current and $L$ is the inductance of the circuit.<\/p>\n<p>The capacitive reactance of a circuit is given by the following equation:<\/p>\n<p>$X_C = \\frac{1}{2\\pi f C}$<\/p>\n<p>where $f$ is the frequency of the current and $C$ <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> is the capacitance of the circuit.<\/p>\n<p>When the inductive and capacitive reactances are equal in magnitude and opposite in sign, the total reactance of the circuit is zero.
