Question : 38 of 50

Marks: +1, -0

Time constant of the network shown in figure is

Solution:

Here, Time constant of the network shown in figure is

R_\eq=(R∥2R)={R×2R}/{R+2R}

={2R}/3

∴ time constant for RC circuit

T=R_\eq.C_\eq

={2R}/3×C={2RC}/3

So the time constant of the network is

={2RC}/3
