1. The voltage v across an inductor L, in LR electrical circuit drops exponentially over time t (s). The relationship is:
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.
See attached for table.
Use your graph to estimate the values of E and τ. How long did it takes to half the initial voltage?© BrainMass Inc. brainmass.com June 4, 2020, 3:53 am ad1c9bdddf

Take logarithm to get,
lnV = -t/tau + lnE
This is in the form of y ...
Given the values for time t and voltage v, a graph is plotted to estimate the values of emf and tau, a constant.
