In figure, capacitor is used to develop pulses of short duration and large duty cycle across R2 when switch is closed. Which of the following combinations is best suited?
R1 and R2 large but C small
R1 and R2 small but C large
R1 and C large and R2 small
R2 and C large but R1 small
Answer: Option
Explanation:

Large values of R1 and C mean large time of charging C and hence large duty cycle. Small value of R2 ensures that duration of pulses is small.
