Question

A 555 timer is connected in monostable operation. If R = 10 k$\Omega$ and C = 22 nF, then the width of the output pulse is equal to ___ $\mu$sec.

• A. 242

Answer 1

The correct option is A 242
$R=10k\Omega :C=22nF$

$\tau =1.1RC=1.1\times 10\times {10}^3\times 22\times {10}^{-9}=242\mu sec$
