Kirchhoff's Laws & Measuring Instruments

The current I flowing through the given circuit will be __________A.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 2

The top wire joins nodes 1 and 3; the bottom wire joins nodes 2 and 4.
So every $9\ \Omega$ resistor lies between the same two points: three in parallel.
$R_{eq} = \frac{9}{3} = 3\ \Omega$ , $I = \frac{6}{3} = 2$ A
So the answer is 2 A.
