Explanation:

a) voltage is more a number of cell are more.Voltage increases hence brightness increases

b) voltage is not same and gets distributed among bulbs in series cuircuit. voltage decreases hence brightness decreases

c) voltage remains same in parallel cuircuit

5) length is small and area or thickness is more. R α l and R α 1/A so resistance is least in the X circuit

Hope the answers are correct
