Abbreviated mA: 1/100 of an Ampere
mA is an abbreviation for milliampere, which is a unit of electrical current. One milliampere is equal to 1/1000 of an ampere (A).
Ampere (A) is the standard unit of electric current, measuring the amount of electrical charge passing a point in a circuit per unit of time.
Here's a breakdown of the relationship between milliamperes and amperes:
- 1 ampere (A) = 1000 milliamperes (mA)
- 1 milliampere (mA) = 0.001 amperes (A)
Why is mA used?
Milliamperes are commonly used in electronics and other applications where dealing with smaller currents is necessary. For example:
- Batteries: The current capacity of batteries is often measured in milliamperes (mAh).
- LEDs: LEDs typically operate at low currents, measured in milliamperes.
- Medical devices: Many medical devices, like pacemakers, use currents in the milliampere range.
Understanding the concept of mA is essential for anyone working with electronics or other applications involving electrical currents.
