How net current on a toroid is zero?​

Physics
1 answer:
Alexxx [7]3 years ago
7 0

Answer:

The concept of zero net current in toroid occurs when we try to determine magnetic field induction outside toroid.

to determine magnetic field outside toroid, we consider a circular loop outside toroid as shown in figure.

to get the net enclosed current inside the loop, let us consider the crosssection AA' in toroid as shown in figure

as we see the crosssection AA' part of figure, we see that currents in the winding are in opposition directions at near to the loop

and far away from loop. Hence the concept of net current zero occurs in toroid when we try to determine

magnetic field induction outside toroid.

A commuter train travels from New York to Washington, DC, and back in 6 hours and 5 minutes. The distance between the two statio
vovikov84 [41]

Answer:

The train's displacement is zero.

Explanation:

Given data,

The time taken by the train from NY to Washington and back is, t = 6 h 5 min

The distance between the two stations is, d = 363 km

Therefore, the total distance the train traveled is, d' = 726 km

The displacement is defined as the change in position coordinates with respect to its original position.

If the train travels from one point and returns back to the same point after some time, there is no change in the position coordinates with respect to its original position.

Hence, the train's displacement is zero.
