1 How many branches and nodes does the circuit in the Figure

1) How many branches and nodes does the circuit in the Figure have? Identify the elements that are in series and in parallel.

Solution

Ans)

A branch represents a single element such as voltage source or a current source or a resistor.

Total 5 branches in this circuit -i.e(1,2,4,5 ohms resistors and 10 V source)

A node is the point of connection between two or more branches.

No of nodes=3

----------

1 ohm and 2 ohms are connected in parallel,similarly 10 V and 4 ohms are connected in parallel,these two parallel circuits are connected in series with 5 ohms resistor
