Question

the circuit [figure.] has t

Answer 1

The total current flowing through the circuit is 2 A.

Answer 2

Resistors $2\Omega$ and $4\Omega$ are in series. Their equivalent resistance is $R_{eq} = 2\Omega + 4\Omega = 6\Omega$. Using Ohm's Law, total current $I = \frac{V}{R_{eq}} = \frac{12V}{6\Omega} = 2A$.
