00:01 Hello everyone so let's start with a question so there is a ninth statement and we have to tell whether this statement is true or false okay so in the first statement it is says that you must have to complete the circuit for current flow okay so suppose this is a circuit okay this is voltage and this is key okay, so this is our key key or you can say switch okay now, so when this switch is off, so there will be no current, okay, so there will be no flow of current but if this switch is on then there will be the flow of current in the circuit and this when the switch is on it is called complete circuit, okay, complete circuit.

00:55 So it is true that for the flow of current the circuit should be completed, okay? so this is true.

01:03 Now in second question, it is says that the in series circuit current flow is in multiple part.

01:08 So let me draw a series connection.

01:12 So suppose there is n number of series, and number of series of register and this is a and this is b.

01:23 So this is r1, r2, r3 and r4 and rn.

01:29 So, if this circuit is completed, like if this circuit is completed, then this current will be going this direction, okay, from high to low and it will enter in this r1, then r2, then r3.

01:45 As you can see that current is flow along a unit directional, as you can see the current is flow in a unit directional flow.

01:53 So from the given diagram, i can say that, i can say that.

01:59 In a series circuit the current flow is multiplier which is false okay which is false so the given statement is false okay now for the third question it is there it is says it is that an open circuit will cause current to flow so as the previous question as you can see if the circuit is closed then there will be the flow of current but if the circuit is open so there will be no flow of current so this statement is false okay this statement is false now, in fourth question, total resistance in a parallel circuits adds all the loads.

02:41 So in parallel circuit, if i draw a parallel circuit, it will look like this.

02:58 So in parallel circuit, as you can see in all the points, in all these points, in all this point, our voltage is same.

03:11 So i can say that v equal to v1, equal to v2, equal to v3.

03:14 And in this current are different, current flow different...
