The equivalent of 1 micro A is: A. 10000A B. 1000 A C. one-millionth of an ampere D. one million amperes E. None of the above

The correct answer is C. 1 microampere is one-millionth of an ampere.

1 microampere is equal to 0.000001 amperes. This is equivalent to 1/1,000,000 of an ampere.

1 microampere is a very small amount of current. It is about the amount of current that flows through a human body when you touch a doorknob.

1 microampere is often used in measuring very small currents, such as those that flow in electronic circuits.
