Question

Quizplus · Accepted Answer

When a 555 timer is operated in the astable mode, it generates a stream of continuous pulses, as it repeatedly charges and discharges a capacitor through a resistor. Therefore, the best choice is C) - stream of pulses. Choices A) and B) are incorrect as they suggest a single pulse or a spike, which are not characteristic of the astable mode. Choice D) is incorrect as it suggests a steady 5 V DC output, which is not possible in the astable mode.
