Milliampere Conversion

A Milliampere (symbol: mA) is a unit of electric current used to measure the flow of electric charge in a circuit. It is a subunit of the ampere (A), which is the standard unit of electric current in the International System of Units (SI).

1. "Milli": The prefix "milli" means one-thousandth (1/1,000) of the base unit. So, 1 milliampere is equal to 0.001 amperes.

2. "Ampere": An ampere (A) is the base unit for measuring electric current. It represents the amount of electric charge flowing through a conductor per second.

• 1 mA = 0.001 A: This means that a milliampere is a smaller unit of current, one-thousandth of an ampere. It is used to measure currents that are more substantial than microamperes but still much smaller than those typically used in household appliances.

• Practical Examples:

  • Batteries: Small batteries, like those in smartphones or remote controls, often supply currents in the milliampere range.
  • LEDs: Light-emitting diodes (LEDs) usually operate with currents of about 10 to 20 milliamperes to produce light.
  • Portable Devices: Many portable electronic devices, such as wearables, operate with currents in the milliampere range to extend battery life.

A milliampere is a unit of electric current that is one-thousandth of an ampere. It is commonly used to measure small to moderate currents in various electronic devices and circuits, where the current is more substantial than microamperes but still smaller than the currents used in larger electrical appliances.
