When this happens, the power consumed by the circuit element is zero.<\/p>\n<p>To understand this, let&#8217;s consider a simple circuit with a resistor. The power consumed by the resistor is given by the equation $P = I^2R$, where $I$ is the current through the resistor and $R$ is the resistance of the resistor.<\/p>\n<p>If the current and voltage are in phase, then the power consumed by the resistor is maximum. This is because the current and voltage are both positive at the same time, so they are both contributing to the power consumption.<\/p>\n<p>However, if the current and voltage are in opposite phase, then the power consumed by the resistor is zero.
