Effects of Placing a Compass Under a Cable
AI Thread Summary
Placing a compass directly under a cable can affect its reading due to the magnetic field generated by the current flowing through the wire. The impact on the compass depends on factors such as the type of cable and the amount of current it carries. A wire with a significant electrical current can create a magnetic field strong enough to influence the compass needle. Understanding how a compass works and the nature of the cable is essential in determining the extent of this effect. Overall, the compass may show deviation when positioned under a current-carrying cable.

What sort of cable? What is happening with the cable?
How does a compass work?
Why might whatever is happening affect a compass?

A wire, and the current go over it ..
NOTE THAT THE COMPASS IS UNDER THE WIRE NOT NAER IT

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.
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...
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...
