# The voltage in a circuit can be modeled by V(1) = V 0 e kt , where t is in

## Question:

The voltage in a circuit can be modeled by V(1) = V_{0}e^{kt}, where t is in milliseconds.

(a) If the voltage decreases by 85% in 5 milliseconds, find k.

(b) If V_{0} = 4.5 volts, find V after 2.3 milliseconds.

(c) By what percentage does the voltage decrease each millisecond?
