A resistor and a capacitor are used in series to control thetiming in the circuit of a heart pacemaker. To design a pacemaker that can double the heart rate when the patient isexercising, which statement below is true? The capacitor(a) needs to discharge faster, so the resistance should bedecreased.(b) needs to discharge faster, so the resistance should beincreased.(c) needs to discharge slower, so the resistance should bedecreased.(d) needs to discharge slower, so the resistance should beincreased.(e) does not affect the timing, regardless of the resistance.

Question
A resistor and a capacitor are used in series to control the
timing in the circuit of a heart pacemaker. To design a pacemaker that can double the heart rate when the patient is
exercising, which statement below is true? The capacitor
(a) needs to discharge faster, so the resistance should be
decreased.
(b) needs to discharge faster, so the resistance should be
increased.
(c) needs to discharge slower, so the resistance should be
decreased.
(d) needs to discharge slower, so the resistance should be
increased.
(e) does not affect the timing, regardless of the resistance.
