Question

Starting with the left-most column, populate the boxes from left to right without skipping empty boxes. Ties should be grouped in the same box. A time constant for an LR circuit is tau having total inductance L and resistance R. Rank the time constants for the following LR circuits, from smallest to largest, given the following values for their resistance and inductance. (They may be ties.) Inductance 3L, resistance 2R Inductance 3L, resistance 3R Inductance 2L, resistance 3R Inductance L, resistance 2R Inductance 2L, resistance 2R Click and drag the options into the described order.

Explanation / Answer

here,

time cosntant for RL circuit , t = L/R

A)

time constant , ta = 3 * L /2 * R = 1.5 t

B)

time constant , tb = 3 * L /3 *R

tb = t

C)

time constant , tc = 2 * L /3 *R

tc = 0.67 * t

D)

time constant , td = 1 * L / 2 *R

td = 0.5 * t

E)

time constant , te = 2 * L / 2*R

te = t

so, time constant from smallest to largest

D < C < (B = E) < A
