Not what you're looking for?
1. The voltage v across an inductor L, in LR electrical circuit drops exponentially over time t (s). The relationship is:
See attached.
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?
