Question Stats:

87% (00:38) correct 12% (00:37) 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. $$3.6*10^{\frac{-8}{3}}$$

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

1,000 times smaller means we divide it by 1,000 which is basically 10^3

So (3.6 * 10^-8)/(10^3) = 3.6 * 10^(-8 -3) = 3.6 * 10^-11
