I graphed Magnetic Field (T) vs Current (A) and my slope was equal to 0.0012 which is off by 10^-3. Can someone suggest why this could be happening?
Finding permability of free space from Magnetic Field vs. Current graph

AI Thread Summary
The discussion centers on a graph plotting Magnetic Field (T) against Current (A), where the calculated slope is 0.0012, deviating by 10^-3. The user converted Magnetic Field data from Gauss to Tesla and provided specific current values in Amperes. Participants are asked to suggest reasons for the slope discrepancy and inquire about the data used for plotting the graph. The conversation emphasizes the importance of accurate data conversion and potential sources of error in the experimental setup. Understanding these factors is crucial for determining the permeability of free space accurately.
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance)
My thoughts for the first case , one of them must be 12 volt while the other is 0
The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
The answer to this question is statements (ii) and (iv) are correct.
(i) This is FALSE because the speed of water in the tap is greater than speed at the water surface
(ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not?
(iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
