1. The problem statement, all variables and given/known data A 5.0V battery is attached to an RL circuit. The current is given by the formula: I = V0/R(1-e-t/τ), where I0 is the steady-state current, and τ is the time constant for the circuit. Using the data table provided, determine τ, R, and L for this circuit. Code (Text): I(mA) | t(μs) --------------- 0 | 0 3.94 | 1 6.32 | 2 7.77 | 3 8.65 | 4 9.18 | 5 9.50 | 6 ... | ... 10.0 | ∞ 2. Relevant equations I = V/R τ = L/R εL = -ε0e-Rt/L I = ε0/R(1-e-Rt/L) 3. The attempt at a solution So I started by concluding that ε0 = V0 = 5 V and I0 = 10 mA. Using that I determined that R = V0/I0 = 5/0.01 = 500 Ω which gives me resistance. I know that once I find τ or L I can easily find the other one, but I can't figure out how to find either of them. At first I thought I could simply work I = V0/R(1-e-t/τ) algebraically to give me τ, but I end up getting undefined from using the natural log with a negative number. I feel like I have to use the data to find one of them (probably τ?) by using the relationship between two of the data points but I'm sort of stuck at this point.
