Suppose the resistors in the various circuits were light bulbs. When a bulb burn

Question

Suppose the resistors in the various circuits were light bulbs. When a bulb burns out it becomes a break in the circuit: this is equivalent to an infinite resistance. In each of the three circuits used, what happens to one bulb when another burns out. Specify whether the bulb goes dark, stays the same brightness, burns brighter or burns more dimly. Assume the battery is an ideal source with no internal resistance. If a bulb in the series circuit of part (A) burns out, what happens to the other bulbs. If a bulb in the parallel circuit of part (B) burns out, what happens to the other bulbs. If in the series-parallel circuit of part (C) if the bulb for R_2 burns out, what happens to R_1 and R_3?

Explanation / Answer

(1)
If the bulb in Series circuit Burns out, Then the other bulb would go dark , as the circuit will be broken !!

(2)
There would be no effect on other bulbs , because of parallel circuit !!

(3)
Please upload picture for third part !!
