Question

What is the use of reset input in the counters?

Comments

all the counters are not free counters, (i.e., after some time it is struck into some state ) then you need reset input to restart the counter.

Answer 1

This is a case where it might be useful.

Suppose you have a 4-bit counter and you want to count only 9 states using your counter. Then you can use the reset input to reset your counter after reaching the state 8 to go back to state 0.Thus making your counter to count only 9 states.
