From the measured currents in Table 3 determine the current through each light bulb /1, 12, 13, I4 and record the values in Table 4.

With all 4 bulbs are in circuit (Fig. 6), use the data in Table 4 explain why bulbs #2 and #3 are dimmer at Vs = 5 V than at Vs = 10 V. 2. Using the measured data of current in Table 3 and the data in Table 4 explain: (a) why bulbs #1 and #4 are brighter than bulbs #2 and #3 at both Vs = 5 V and 10 V when all the 4 bulbs are in circuit
