Voltage in a circuit

Question

Answer 1

Step 1 :

Resistors R₅ and R₆ are in parallel.

Find the equivalent parallel resistance.

Redraw the network replacing equivalent parallel resistance.

Convert the delta network into star network.

Step 2 :

Redraw the network with star connection.

Resistors R_C  and R_B are in parallel.

Now the resistor R_A is in series with R_p.

Resistors R_q  and R₁ are in parallel.

Step 3 :

Redraw the equivalent network.

Apply the KVL to the equivalent network.

Step 4 :

Find the voltage across the nodes A and B.

Voltage across the nodes A and B is .

Solution :

Voltage across the node s A and B is .
