Step 1 :

\

Redraw the circuit.

\

$\"\"$

\

Observe the diagram.

\

The current flows directly so we can not consider the resistor $\"\"$ .

\

The resistors $\"\"$ and $\"\"$ are in seies.

\

$\"\"$

\

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

\

$\"\"$

\

Current $\"\"$ .

\

$\"\"$

\

Step 2 :

\

Find current running through $\"\"$ .

\

Current Division Rule : $\"\"$ .

\

$\"\"$

\

Therefore, current running through $\"\"$ is $\"\"$ .

\

Step 3 :

\

Find current running through $\"\"$ .

\

$\"\"$

\

Substitute corresponding values in the above equation.

\

$\"\"$

\

Therefore, current running through $\"\"$ is $\"\"$ .

\

Power $\"\"$ .

\

Substitute corresponding values in the above equation.

\

$\"\"$

\

Power dissipated on $\"\"$ is $\"\"$ .

\
