Hey guys, have a question on a homework assignment related to RL time constants.
"A constant voltage is applied to a RL circuit at time t=0. The voltage across the inductance is 20 V at 3.46ms and 5 V at 25ms. Obtain R if L = 2H."
Given the equation T(tau/time const.) = L / R, how do I first calculate the time constant of the circuit in order to calculate the resistance?
