Step 1 :

\

Observe the diagram :

\

The resistors $\"\"$ and $\"\"$ in parallel connection.

\

Equivalent resistance connected in parallel is $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Parallel equivalent resistance : $\"\"$ .

\

Step 2 :

\

The Resistors $\"\"$ and $\"\"$ in series connection.

\

Equivalent resistance connected in series is $\"\"$ .

\

$\"\"$

\

Series equivalent resistance : $\"\"$ .

\

Step 3 :

\

The total resistace of $\"\"$ is the resultant resistance of $\"\"$ and $\"\"$ .

\

The resistors $\"\"$ and $\"\"$ are connected in parallel connection.

\

Equivalent resistance connected in parallel is $\"\"$ .

\

$\"\"$

\

Total resistance of the circuit between $\"\"$ and $\"\"$ $\"\"$ .

\

Solution :

\

Total resistance of the circuit between $\"\"$ and $\"\"$ $\"\"$ .
