The current supplied by a battery as a function of time is i(t) = (0.88 a) e^(-t*6 hr). what is the total number of electrons transported from the positive electrode to the negative electrode from the time the battery is first used until it is essentially dead?
3.7 x 10^18
5.3 x 10^23
4.4 x 10^22
1.6 x 10^19
1.2 x 10^23

Explanation:

As we know that the current through the battery is given as

here from above equation we know that current will become zero when time elapsed is very large

so here we can say that charge will flow through the battery from t = 0 to t = infinite

now we have

As we know that

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.
