Question

Which of the following NOT true about a series circuit?
(A)All the bulbs will glow when the circuit is closed
(B)If any of the bulb gets fused, then the other bulbs also stop glowing
(C)The bulb do not glow brightly
(D)All the bulbs glow independently

Answer 1

Answer:

(D)All the bulbs glow independently

Explanation:

Answer 2

Among the following statements, the false(not true) statement is: All the bulb glows independently. (Option D)

• In a series circuit, the glowing of the bulbs is dependent. Either all of them glow or none of them glows.
• If one bulb is damaged, the remaining bulbs also do not glow. Therefore, option D is not true.
• Circuits work only when they are closed. For all the bulbs to glow, the circuit has to be closed. Option A is true.
• In a series connection, the current flows through a single path through all the bulbs, so if one bulb gets fused, it obstructs the current flow and the bulbs stop glowing. Option B is true.
• In a series circuit, the voltage across each bulb is different and also less than the net voltage, therefore the bulbs do not glow brightly. Option C is true.
