Hello guys i'm here to show this problem so the switch in the circuit shown below has been open for a long time so first of all we need to find the what is the current through 5 -oom register immediately after this switch is closed so we make a diagram to understand this problem so here it is a switch it stands and a capacitor is also here battery is connected so it is a circuit diagram which is given in our fusion.
00:28
It is 10 -on, it is 15 -oom and they both are connected in parallel.
00:33
So it is the 4 microferral capacitor and the battery of 10 volt and a resistance is also here.
00:41
It's 5 -home register and it is a switch.
00:45
So it is a diagram which is given in -o now let's start our solution.
00:48
So first of all 15 -oom and 10 -o -on registers are connected in parallel.
00:55
So the equivalent resistance 1 upon 1 divided by r is equal to 1 divided by 15 plus 1 divide by 10.
01:04
So the value of r is equal to 6.
01:07
Now in the first question, so it is the 25 number question.
01:11
So in this question, we need to find the current in the 5 -home register...
