Assignment:
The voltage v across an inductor L, in LR electrical circuit drops exponentially over time t (s). The relationship is:
v = Ee-t/τ
Where the emf, E, and τ are constants. Use the table of values for t and v and logarithms to plot an appropriate straight line graphs.
t 0.00 0.010 0.020 0.025 0.030 0.040 0.050
v 5.50 2.950 1.600 1.150 0.850 0.450 0.250
Use your graph to estimate the values of E and τ. How long did it takes to half the initial voltage?
Provide complete and step by step solution for the question and show calculations and use formulas.
