What is the current entering the node.

The Attempt at a Solution

I=V/R
P=IV -> 510/.470=1085V
R(Inductor)=wL -> 2pi*60*1.25 = 471.24
R(Resistor)=V/I -> 1085/0.47 = 2308.74
R(Total)= sqrt(R(Resistor)^2+R(Inductor)^2) -> 2356.12
V=sqrt(2)*V(RMS) -> 1534.42
I=V/R -> 1534.42/2356.12 = 0.65A

I=V/R
P=IV -> 510/.470=1085V
R(Inductor)=wL -> 2pi*60*1.25 = 471.24 Reactance in OHMS
R(Resistor)=V/I -> 1085/0.47 = 2308.74 OHMS
R(Total)= sqrt(R(Resistor)^2+R(Inductor)^2) -> 2356.12
You can't do this for parallel circuits. You have to work out the currents and then put them in the right angled triangle.

Don't forget that reactance is the term for the impedance of inductors and capacitors, not resistance which is purely for resistors.

I would like to commend you on your attempt at solving the problem. It seems like you have correctly used Ohm's Law and the equations for calculating power and impedance. However, it would be helpful to provide some context for the problem, such as the circuit diagram or any additional information given. This will help in verifying the accuracy of your calculations and providing a more comprehensive solution. Additionally, it would be beneficial to clearly label your equations and show your steps in solving the problem. This will make it easier for others to follow your thought process and understand your solution. Overall, good job on using the relevant equations and providing a numerical answer. Keep up the good work!
