Question Stats:

100% (00:52) correct 0% (00:00) wrong based on 8 sessions
The microcurrent through the electrode in a delicate circuit is usually held constant at \(3.6*10^{(-8)}\) amps. Because of a defect in another part of the circuit, the current was 1,000 times smaller. What was the current, in amps, caused by this defect?


A. \(3.6 * 10^{(-8000)}\)

B. \(3.6 * 10^{(-24)}\)

C. \(3.6 * 10^{(-11)}\)

D. \(3.6 * 10^{(-5)}\)

E. \(3.6 * 10^{(-\frac{8}{3})}\)


Kudos for correct solution.

The microcurrent is usually held at 3.6*10^{(-8)} however this has to be reduced by 1000 times or 10^3
If we multiply 3.6*10^{(-8)} by 10^3 we get 3.6*10^{(-5)} which is bigger than the original number not smaller
so we have to multiply 3.6*10^{(-8)} by 10^{(-3)}

Just divide the given equation 3.6*(1e-8) by 1.000 (or 10³) to get 3.6*(1e-11).
-> Answer C is correct
