The time constant to reach full charge in an RL circuit is 0.05 ms.
Explanation:
To find the time constant,
The time constant for an RL circuit is defined by τ = L/R.
The given data is
L= 5 H
R= 100 ohms
by using the formula,
τ = L/R
= 5/100
= 0.05 ms
τ = 0.05 ms
Thus, the time constant to reach full charge in an RL circuit is 0.05 ms.
