Quizplus · Accepted Answer

An RC integrator circuit uses a capacitor and a resistor to control the timing of the output voltage. The time constant of the circuit is given by RC. If the capacitor increases in value, the time constant increases, and it will take longer for the output voltage to reach the threshold required to turn on the circuit. Therefore, the most probable cause of the circuit taking longer to turn on is an increase in the value of the capacitor.
