Could someone please help me with thus physics question? A quick explanation is only needed with the answer as I do not want you to spend to much time

(2) (50 pts.) In the circuit shown in the figure, three identical light bulbs are connected to a flashlight battery. (a) How do the brightnesses of the bulbs compare? (b) Which light bulb has the greatest current passing through it? (c) Which light bulb has the greatest potential difference between its termi- nals? (d) What happens if bulb A is unscrewed (clearly bulb A goes out, but what happens to the brightness of bulbs B and C)? (e) What happens if bulb C is unscrewed (clearly bulb C goes out, but what happens to the brightness of bulbs A and B)? 3 + A B C
