Question

Problem 3 (Explanation Task) X (It is not necessary to use the solution format for this problem.) 2 1. Consider the circuit shown at right, which is a variant of the circuit from studio. All bulbs are identical, and all batteries are ideal and identical. (Note that the orientation of battery D has changed.) Y D A. Is bulb 2 brighter than, dimmer than, or as bright as bulb 1? Explain your reasoning Z B. Sketch appropriate voltage diagrams for this circuit. you C. Use your diagrams to rank the voltages V1, V2, Vc, and Vy from greatest to least. Explain how determined your answer. D. On the circuit diagram, draw arrows to indicate the direction of the current through each battery and each bulb. E. Rank the currents 11, 12, Ic, and Ip from greatest to least. Explain how you determined your answer. F. Suppose that bulb 1 were removed, leaving a gap in the circuit. Would this cause bulb 2 to get brighter, less bright, or to stay the same brightness? Explain. G. Suppose that battery C were removed, leaving a gap in the circuit. Would this cause bulbs 1 and 2 to get brighter, less bright, or to stay the same brightness? Explain.

Answer 1

from KVL law, A) 닌 V 2 01 1 V, EV V - V₂ +VD z كم V + V so bulb 2 is brighter than bulbs ID B) f I Ic Fe- ID) (3V2 واكه 잇 V = V 7 > Vo v = vo] D) Already drawn above v> and I Em R, = R₂ Iz LI - Ig> I also I t Iz Ic> I2 = ID > I no effect i.e. i.e. bulb 2 will have some brighten billy i way in parallel. since
