Answer:
Time constant of RC circuit is 0.105 seconds.
Explanation:
It is given that,
Resistance, [tex]R=50\ K\Omega=5\times 10^4\ \Omega[/tex]
Capacitance, [tex]C=2.1\ \mu F=2.1\times 10^{-6}\ F[/tex]
We need to find the expected time constant for this RC circuit. It can be calculated as :
[tex]\tau=R\times C[/tex]
[tex]\tau=5\times 10^4\times 2.1\times 10^{-6}[/tex]
[tex]\tau=0.105\ s[/tex]
So, the time constant for this RC circuit is 0.105 seconds. Hence, this is the required solution.
