of bulbs from Fig. 3(a) to Fig. 3(d)? Why?
2. Is there any correlation between the measured current and observed brightness? If yes, is the correlation consistent with P = IV = I^2R?

3. Are the lights at your home connected in parallel? Why?
4. The maximum output current from the power supply (HY152A) is 2 A. what is the maximum number of light bulbs (used in this experiment) that can be connected in parallel with the power supply (HY152A)? What will happen if more than 10 such light bulbs are connected in parallel with the power supply (HY152A)?
Experiment 3.4 1. Using the data from Table 4, explain why bulb #2 and #3 are brighter at Vs = 10 V than at Vs = 5 V?
2. Why is bulbs #1 and #4 brighter than bulbs #2 and #3 at both Vs = 4.830 V and 10 V when all the 4 bulbs are in circuit? 3. Why does bulb #3 become brighter after bulb #2 is removed (all other bulbs are remained
in the circuit)?
4. Can the lights at your home be connected as shown in Fig. 4? Why?
