Correct Answer

D

Explanation

I = v/R = 12/12 = 1.0ATo find the current flowing through the 12Ω resistor in the given circuit, we can use Ohm's Law and the concept of parallel resistors.

In a parallel circuit, the voltage across each resistor is the same. Therefore, the voltage across the 12Ω resistor is also 12V.

Using Ohm's Law (V = IR), we can calculate the current (I) flowing through the 12Ω resistor by rearranging the formula:

I = V / R

Substituting the values, we have:

I = 12V / 12Ω

Simplifying the expression, we find:

I = 1A

Therefore, the current flowing through the 12Ω resistor is 1 Ampere.
