Step 1:

\

Observe the circuit,

\

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

\

Resultant resistance is $\"\"$ .

\

$\"\"$

\

Above resultant resistance is in series with $\"\"$ .

\

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

\

$\"\"$

\

$\"\"$ .

\

Find the current passing through the circuit.

\

$\"\"$

\

$\"\"$ .

\

Find the voltage drop across the resistance $\"\"$ .

\

$\"\"$ .

\

$\"\"$ .

\

Voltage drop across the resistors $\"\"$ and $\"\"$ is same since they are in parallel.

\

$\"\"$

\

Find the current flowing thriugh the resistor $\"\"$ .

$\"\"$ .

\

Find the current flowing thriugh the resistor $\"\"$ .

\

$\"\"$

\

$\"\"$ .

\

Solution:

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

\

Current passing through the amperemeter is $\"\"$ A.
