An IC 555 chip has been used to construct a pulse generator. Typical pin connections with components is shown below in fig. for such application. However it is desired to generate a square pulse of 10KHz..
Evaluate values of $${R_{A\,}}$$ and $${R_{B\,}}$$ and if the capacitor has the value of 0.01$$\mu $$F for the configuration closed. If necessary you can suggest modifications in the external circuit configuration.
