A 12 V battery is connected to three light bulbs in a parallel circuit. Each light bulb is different: the first has a resistance of 10 ohms, the second has a resistance of 20 ohms, and the third has an electrical resistance of 30 ohms. Calculate the equivalent resistance of the three bulbs in parallel.
