First, calculate the equivalent resistance (Req) of the parallel combination:
Req = (R1 * R2) / (R1 + R2) = (5Ω * 10Ω) / (5Ω + 10Ω) = 50Ω / 15Ω = 3.33Ω (approximately)
Next, use Ohm's Law (V = IR) to calculate the total current (I) flowing from the battery:
I = V / Req = 12V / 3.33Ω = 3.6A (approximately)
Therefore, the equivalent resistance of the parallel combination is approximately 3.33Ω and the total current flowing from the battery is approximately 3.6A.
