Max Power of Resistor in 3-Resistor Circuit

Click For Summary

Homework Help Overview

The discussion revolves around a circuit problem involving three 100-ohm resistors and the maximum power that can be delivered to any one resistor, which is specified as 28.0 W. Participants are exploring how to determine the current and voltage in the circuit based on this information.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss calculating the total resistance and the current flowing through the resistors. There is a suggestion to use Ohm's law to find the voltage from the power delivered to the resistors. One participant seeks clarification on whether they are looking for the voltage across a specific resistor or between two points in the circuit.

Discussion Status

The discussion has seen various attempts to clarify the problem and explore different aspects of the circuit. One participant has indicated they found the answer they were looking for, specifically the maximum voltage to each resistor, but the details of this conclusion are not shared.

Contextual Notes

There is an implicit assumption about the configuration of the resistors and how they are connected, which may affect the calculations. The original poster's initial uncertainty about how to proceed indicates potential gaps in understanding the circuit's behavior.

The Attempt at a Solution


I found the total resistance of the circuit, but i don't know how to get the current, which i need for the voltage

The maximum current flows through the resistor on the left. So, if you calculate that current (from the power), you can get the voltage by using Ohm's law.

I'm not sure if this is correct.
 
Could you be a little more clear about what you want to solve? For example do you want voltage across any particular resistor or voltage between A and B?

never mind ...i found the answer. What i wanted was the maximum voltage to each resistor.
