Homework Help Overview

The discussion revolves around a problem related to calculating current (I) in a circuit, likely involving concepts from electromagnetism or circuit analysis. Participants are attempting to solve for current using a formula that incorporates magnetic field strength, velocity, and resistance.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are sharing their attempts at calculating the current, with some expressing uncertainty about their results and questioning the accuracy of their calculations. There are discussions about unit conversions and the specific resistance to consider in the calculations.

Discussion Status

The discussion is ongoing, with participants providing feedback on each other's calculations and pointing out potential errors. Some guidance has been offered regarding unit conversions and the resistance to use, but there is no clear consensus on the correct answer yet.

Contextual Notes

There are mentions of specific values and units, such as resistance in ohms and the need to convert centimeters to meters, which may impact the calculations. Participants are also navigating through the implications of using different lengths of resistance in their calculations.

parta=4.274A
partb=clockwise
partc=0A
partd=no direction
parte=4.273A
partf=anti-clockwise...
you didn't convert cm unit into meter...hope this was helpful...
 
if that's right than I must just have a wrong exponent somewhere
 
mind telling me how you got that because I checked mine and I keep getting 0.00427A??
 
yupe...you correct...its 0.0427...sorry for previous answer and inconvinience...so wats the problem now...you getting the answer...
 
No,thats not the answer, I tried that but it tells me its incorrect.
 
here the resistance 3.5ohm is of the whole loop.But,we have to consider resistance of only the length of the side which we are considering in calculation...
R=(3.5*8)/40.
now do calculation and hope you will get the answer... :)
