A given circuit using an RC integrator to turn on after 20 seconds now takes now takes much longer to turn on. What is the most probable cause?
A)The capacitor has decreased in value.
B)The resistor has decreased in value.
C)The capacitor has increased in value.
D)The resistor has opened.

Question

Quizplus · Accepted Answer

The time constant of an RC integrator is determined by the product of the resistance (R) and the capacitance (C). If the circuit takes longer to turn on, it suggests that the time constant has increased, which would occur if the capacitance has increased.
