SHOW WORK PLEASE!

In the example shown below, current travels through the inductor in the direction indicated, and is increasing with time. Which of the following is true? A. Point 1 is at higher potential than point 2 B. Point 2 is at higher potential than point 1 C. Points 1 and 2 are at the same potential An inductor has a potential difference of magnitude 0.06 V across it. The current through the inductor is 1.5 A and the current is changing at a rate of 2.5 A/s. What is the inductance? A. 60.0 mH B. 40.0 mH C. 24.0 mH D. 0 mH

Explanation / Answer

1)

Since the current is increasing,then induced emf opposes the change in current ,and now the inductor acts as a source of emf or battery ,to oppose the change in current the diretion of induced current in coil is from 1 to 2 ,i.e inside the battery current flows from low potential to high potential

So TRUE statement is

B) point 2 is at higher potential than point 1

2) inductane is L

we know that emf e = L*di/dt

L = e/(di/dt) = 0.06/(2.5)

L = 24 mH

so correct choice is C) 24 mH
