So here a table is given for the rc circuit discharging experiment.
00:10
We are required to draw a graph of the tabulated result.
00:15
First of all, i want to let you know an equation for discharging rc circuit which is given as vc is equal to vv, exponential of minus t divided by rc, where rc is the time constant.
00:32
And t is the time we can write let us plot we can we can we can now have a rough estimate that this is obviously gone and exponentially decreasing because this is we see for t is equal to zero let we have this 20 i have this 20 here again for t is equal to 360 seconds we have 0.
01:30
Now suppose t is equal to 30, suppose t is equal to 30, let it be here, have nearly 11 seconds, 10 .98, so we have this.
01:47
Again for t is equal to 60, we have 6 .20.
01:56
Let it be here some.
02:00
If we just calculate in this way, which is pretty much easy, this is 30, this is 6.
02:06
This is 6 .02, this is 10, this is 10 .98.
02:14
Then this is 120.
02:16
We have 1 .81.
02:22
Here it...
