Final answer:
The term that represents 0.001 ampere is 'C. Milliampere', which signifies one thousandth of an ampere.
Step-by-step explanation:
The term that means 0.001 ampere is C. Milliampere. 'Milli' is the metric system prefix that denotes a factor of one thousandth, which implies a multiplication by 10-3. Therefore, one milliampere (mA) is equal to 0.001 amperes (A). The ampere is the SI unit for current, with the definition that one Ampere equals one Coulomb per second (1 A = 1 C/s). This term is often used when discussing electrical currents, particularly those that are relatively small, such as in bioelectricity or electronic circuits.
