Question “PSS 26.1 Resistors in Series and Parallel Learning Goal: To practice Problem-Solving Strategy 26.1 Resistors in…”
PSS 26.1 Resistors in Series and Parallel Learning Goal: To practice Problem-Solving Strategy 26.1 Resistors in Series and Parallel. Part A Two bulbs are connected in parallel across a source of emf = 12.0 V with a negligible internal resistance. One bulb has a resistance of 3.0 2, and the other is 3.5 . A resistor R is connected in Which of the following circuit diagrams represents the circuit described in this problem? A 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? C D R: Please Choose
Part B Which of the following statements are correct for the circuit described in this problem? Check all that apply. Each bulb will have a different voltage, which will depend upon its individual resistance. The voltage across each bulb will be the same, regardless of their different individual resistances. The current flowing through each bulb will be the same, regardless of their different individual resistances. The total current flowing through the two-bulb combination equals that passing through resistor R Request Answer Submit

Sol.) Sol.) It shows both resistance R in series to each other and blbs in parallel. Both options he and d are correct. In barallel combination, voltage across barallellines is the same regardless of resistance. Junction law will dictate that the corrent through R is the sum of both bulbs’ currents. We have circuit.
Het or So R., and R of equivalent bulb resistance hare the resistances 1, and 2, respectively. Resistance is Req = + +1 E => Reg. = R1 R2 RitR (3) (3.5) = 1.5152 3+3.5 voltage drop across the R and Rq should equal 2.4v So I Req = 24V-W and IR12 -2.451. -cij Divides is by adR? 2.4 9.6 9.6 Req 2.4 – 4 Reqa Ra 4x 1.6152 = 6.46152
Sola) across a 764 0.8 Amb. 3.0 and current through bulb 2 Thor 2-3 Amb. A 0.6857 Amb. 3.5
