One micro ampere electric current is equal to

Correct option is C

• Micro is a metric prefix that denotes a factor of 10⁻⁶. Hence, one microampere (1 µA) is equal to 1 × 10⁻⁶ amperes (A).
• This can be derived from the fact that the prefix "micro" corresponds to one-millionth, or 10⁻⁶.
  

• Microampere (µA) is a common unit for measuring very small electric currents, often used in electronics and sensitive instrumentation.
• The symbol µA stands for "micro" (μ) as the metric prefix, and it means one-millionth (1/1,000,000) of an ampere.
• 1 µA = 10⁻⁶ A is the relationship used in electrical engineering and physics for current measurement.
• The ampere (A) is the SI base unit for electric current, and microampere is often used in contexts like electronic circuits, biosensors, and other low-current applications.
• In scientific notation, 10⁻⁶ A is the correct representation of microamperes. This allows easier comparison of magnitudes of current.
• Microampere is typically used for measuring currents in applications like human body electrical measurement, small sensors, and circuits that operate at low power.
