Consider the power dissipated in a series r–l–c circuit with r=280ω, l=100mh, c=0.800μf, v=50v, and ω=10500rad/s. the current and the voltages in this circuit are not in phase with each other. using the values given, the phase angle ϕ was found to be 73 ∘, and the current amplitude i was found to be 5.1×10−2 a . calculate the power factor and the average power to the entire circuit and to each circuit element.
