Duality (electrical circuits)

<p>In <a href="/facts/Electrical_engineering/YYXW1KLW">electrical engineering</a>, electrical terms are associated into pairs called duals.  A dual of a relationship is formed by interchanging <a href="/facts/Voltage/EN2po6N2">voltage</a> and <a href="/facts/Electric_current/Dc1xdnUX">current</a> in an expression. The dual expression thus produced is of the same form, and the reason that the dual is always a valid statement can be traced to the <a href="/facts/Duality_(electricity_and_magnetism)/wnUElqzv">duality of electricity and magnetism</a>.
