Step 1:

Observe the circuit.

The resistors $\"\"$ , $\"\"$ and $\"\"$ are in parallel.

Resultant resistance is $\"\"$ .

Substitute $\"\"$ in above expression.

$\"\"$

$\"\"$

Resultant resistance is $\"\"$ .

Observe the circuit, the resistors $\"\"$ and $\"\"$ .

Resultant resistance is

$\"\"$

$\"\"$

The resistors $\"\"$ and $\"\"$ are connected in series.

Equivalent resistance is $\"\"$ .

$\"\"$ .

Step 2:

Redraw the circuit replacing the resistor $\"\"$ , $\"\"$ , $\"\"$ , $\"\"$ and $\"\"$ by $\"\"$ .

$\"\"$

Observe the circuit :

The resistor $\"\"$ is in parallel with $\"\"$ .

Therefore, resultant resistance is $\"\"$ .

$\"\"$

$\"\"$ .

The resultant is in series with the resistance $\"\"$ .

Therefore, total resistance of the circuit is $\"\"$ .

$\"\"$ .

Total resistance of the circuit is $\"\"$ .

Solution :

Total resistance of the circuit is $\"\"$ .
