Weiss's Law According to Weiss's law of excitation of tissue, the strength $S$ of an electric current is related to the time $t$ the current takes to excite tissue by the formula

$)>(0$

where a and $b$ are positive constants.

$($a$)$ Evaluate $\underset{t{0}^{+}}{lim}S(t).($If the limit is infinite, enter $\text{'}\text{'}$ or $\text{'}-\text{'},$ as appropriate. If the limit does not otherwise exist, enter DNE.$)$

$\underset{t{0}^{+}}{lim}S(t)=$

Interpret your result.

As the time taken to excite the tissue is mact shorter and shorter, the strength of the electric current gets stronger and stronger.

As the time taken to excite the tissue is made longer and longer, the strength of the electric current gets weaker and weaker.

$\underset{t}{lim}S(t)=$

Interpret your result.

As the time taken to excite the tissue is made shorter and shorter, the strength of the electric current gets stronger and stronger and approaches $b.$

As the time taken to excite the tissue is made longer and longer, the strength of the electric current gets weaker and weaker and approaches $b.$
