00:01 Hello students, let's discuss the question.

00:02 So here we have three sub -questions.

00:04 Firstly, we need to find the effect on charging and discharging times if the capacitance is increased and what will be the mathematical relation which exists between the time and the capacitance.

00:15 Secondly, we need to find what will be the effect on the total capacitance if capacitors are combined in the series.

00:21 And thirdly, we need to find what is the effect on charging and discharging time if the resistance of the circuit is increased.

00:28 So here let's start.

00:29 So here we can say that time t is related to capacitance c over here.

00:47 This is for the first one.

00:48 We are solving for the first option.

00:50 So here we can say that time is related to the capacity.

00:53 So here we can say q is equal to c.

00:56 Y o multiplied by 1 minus e whole raise to minus t divided by rc.

01:03 That will be equal to q0 multiplied by 1 minus e whole raise to minus t divided by rc.

01:10 So here we can say this is equal to t that is equal to rc divided by rc multiplied by lr multiplied by q0 -9 minus q divided by q.

01:26 So this is the formula over here.

01:28 So here we can say that the capacitance is increased charging time...
