Hi, here in this given problem, the current electric current passing through d fibrillator that is given as i is equal to 12 .5 ampere.
00:38
It is allowed to pass for a time t is equal to 5 .00 milliseconds.
00:47
So, using a fundamental definition for current, electric current, that is given as the time rate of flow of charge through any cross section of the conductor.
01:04
So using that we get an expression for the charge passing through the conductor.
01:09
Here it will be the charge passing through the torso and that will be i into t means 17 .5 ampere multiplied by 5 milliseconds or 5 into 10 to the power minus 3 second.
01:24
So this charge is calculated to be equal to 62 .5 into 10 to the power minus 3 coulum or we can say this is 6 .25 into 10 dash the power minus 2 column which is one of the answer for this given problem.
01:50
Then in the same problem, energy dissipated in the patient's body that has been given as u is equal to 515 joules.
02:12
So using an expression for electric energy, that is u is equal to v into i into t where v is the potential difference applied across the patient's body.
02:34
So we get an expression for the potential difference applied across the body that is u by i into t.
02:42
So here it will be 515 juice divided by i into t means 12 .5 into 5 into 10 dash to the power minus 3.
02:55
And it is calculated to be equal to 8 .24 into 10 to the part 3 volt.
