To practice Problem-Solving Strategy 26.1 Resistors in Series and Parallel.

Two bulbs are connected in parallel across a source of emf E = 12.0 V with a negligible internal resistance. One bulb has a resistance of 3.0 Ω , and the other is 2.5 Ω . 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 ?

Part C

For what value of R would the potential difference across each of the bulbs be 2.4 V ?

Express your answer in ohms using three significant figures.

R =
Ω

ough the bulb of resistance 3.0 Ω, and Ib2 the current through the bulb of resistance 2.0 Ω .

Enter each current value in amperes using three significant figures and separated by commas.

Ib1, Ib2 =

A, A
