Question: Two bulbs are connected in parallel across a source of emf E = 12.0V with a negligible internal resistance. One bulb has a resistance of 3.0ohms , and the other is 4.0 ohms . A resistor R is connected in the circuit in series with the two bulbs. What value of R should be chosen in order to supply each bulb with a voltage of 2.4 V? For what value of R would the potential difference across each of the bulbs be 2.4 V?
