Hi, can you please check my answer? I am not confident because the power consumption seems too small. By the way, we don't use calculator at all so we don't have to calculate to the exact value. For example, if there is "pi", we can just leave it as it is, without converting it into 3.142. Also, if there is square root of 2, just leave it as square root of 2, no need to calculate it as 1.41. Ok, here is the question: v1(t) and v2(t) are given as written in the question. 1) Find the value of impedance Z. 2) Find the power consumption (effective power) of the entire circuit.
