- Knowing the units of R and L and using dimensional
analysis, can you predict
a relation between R and L that will result in a time value (units of seconds)?
Justify your prediction. Using this prediction, theoretically predict the
time for this circuit. How does it compare to the experimental value you
- Describe the current buildup process
for an R-L circuit [see the Fig. HW-21], and
the associated time constant, t.
(a) If the coil has an inductance of 1.5H and a
resistance of 0.6W,
and the coil is suddenly connected across a 12-V battery, find
the time required for the current to rise to 0.63 of its final value. (b)
be the final current through the coil?
