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. $$3.6 * 10^{(-5)}$$
