Homework Statement

See Attachment.

Find the total Current in the following circuit by phasor diagram techniques only. What is the total power dissipated?Do not use complex #'s.

Homework Equations

The Attempt at a Solution

Im not really sure how to start and the notes for this topic arent that great. I have done a few examples involving a series cct and parallel cct, but I haven't seen one like this.


Any help would be appreciated.
Thanks

EDIT: Could someone move this into engineering/computer science section?

So, what is the equivalent phaser resistances for capacitors and inductors? Once you convert your supply to phaser form, and the resistances to phaser form all of the regular circuit techniques can be applied. I am really confused by the "do not use complex numbers" statement. It's like saying, "You must use phasers! Oh, I'm sorry, I meant phasers without complex numbers (?)."

I would start by analyzing the circuit diagram and identifying all the components and their values. From there, I would use basic circuit analysis techniques such as Ohm's law and Kirchhoff's laws to calculate the current and power dissipation in the circuit.

First, I would calculate the total resistance in the circuit by combining the resistances in series and parallel. Then, using Ohm's law (V=IR), I would calculate the total voltage in the circuit. From there, I can use Kirchhoff's laws to determine the current at each point in the circuit.

To calculate power dissipation, I would use the formula P=IV, where I is the current and V is the voltage. I would calculate the power dissipation at each component in the circuit and then add them together to get the total power dissipation.

Using phasor diagram techniques, I would represent the voltages and currents in the circuit as vectors and use vector addition to find the total current. This method is particularly useful for analyzing AC circuits.

Overall, the key to solving this problem is to have a solid understanding of basic circuit analysis techniques and to carefully apply them to the circuit diagram.
