00:01 Hi, this is a question based on the circuit analysis.

00:04 So we have to find the number of branches and number of nodes.

00:08 So first let us find the branches.

00:10 So this is a branch, this is a branch and this is a branch and so this is a branch and here this is a branch.

00:21 So capacitor forms a branch, this resistor, this resistor, this and this forms the batch.

00:27 So we have the number of branches is, so number of branches is a, b, c, d and e.

00:36 Therefore five branches.

00:38 Then we have to find the node.

00:40 So node is nothing but it is the closed loop form.

00:45 So here this closed loop is, so the number of closed loop is, so here, so this point forms a closed loop.

00:55 So the current passes through this resistor.

00:57 So this is a node, then here this forms a point, which is a node.

01:07 So this is another node.

01:09 Then so here the point c is grounded.

01:16 So this is another node, that is node 3.

01:20 So here 1, 2, 3 forms the node.

01:22 So which is in this circuit.

01:24 Therefore we have number of nodes is equal to, so nodes is equal to 1, 2, 3.

01:32 Therefore three nodes.

01:35 So here we can see that 1 ohm resistor is in parallel with 2 ohm resistor...
