Quizplus · Accepted Answer

Connecting the control voltage pin of a 555 timer to ground through a resistor affects the threshold at which the timer's internal flip-flop is reset, leading to a shorter on time in a typical astable configuration. The off time is determined by a separate part of the circuit and remains unchanged by this modification.
