Pacemakers designed for long-term use commonly employ a lithium-iodine battery capable of supplying 0.42a⋅h of charge. part ahow many coulombs of charge can such a battery supply? part bif the average current produced by the pacemaker is 5.6μa, what is the expected lifetime of the device?

A) Charge supplied: 1512 C

The battery in this problem supplies a charge of:

where the charge is written in the form:

where I is the current and t is the time elapsed. We have:

is the current

is the time elapsed

Substituting in the equation, we find

B) Expected lifetime:

The average current produced by the pacemaker is

While the total charge available is

Q = 1512 C

Therefore, the expected lifetime is

which corresponds approximately to 8.56 years.

the answer is false
