Hi students in this question, the magnetic flux versus time graph for the case of a single loop coil is given and we are asked to find out the value of induce emf related to this particular coil.
00:12
And the equation this is used for finding the induced emf is taken as e to v equal to n into d5 by dt where this d5 by dt corresponds to the slope of this graph while n corresponds the number of turns of that coil.
00:29
And in this case since we are dealing with a single loop coil, the value of n will be equal to 1, thereby the equation of e changes as a value of d5 by dt.
00:40
Now here we are asked to find out the value of e for three different times, that is t is equal to 0 .05 seconds, t is equal to 0 .15 seconds, and finally for t is equal to 0 .50 seconds.
00:57
Now first we can find it for the case of t is equal to 0 .0 .0 seconds.
01:03
And for this, let us take the induced emf as e1, which is equal to d5 by dt.
01:10
Now from this graph, we can say that the value of d5 by dt will be equal to 10 minus 0 divided by 0 .1 minus 0.
01:21
Now by simplification we get the value of e1 to be equal to 100 volts.
01:27
Now for the time period of t is equal to 0 .15 seconds, the induce emf is taken as e2 which is equal to d5 by dt...
