![]() The milliampere has its origins in the ampere. Current measurements may be measured in either amperes or milliamperes. It is equal to the amount of current that would generate an electric force of 2 x 10-7 Newtons per meter if it were allowed to pass through two parallel infinite length conductors separated by one meter in a vacuum with a very small cross-sectional area. ![]() A milliampere is another term for a milliamp.Īn ampere is the SI unit used to measure electric current. As a result, a milliamp equals 0.001 amperes. One-thousandth of an ampere is equal to one milliamp. Electrical current is measured in amperes (or amps) and abbreviated as “A” in the international system of measurements (SI units). A current of 1 mA can give a faint prickly sensation in a 60-cycle per second electric shock that runs from the hand to the foot, whereas a current of more than 2,000 mA can cause heart failure, severe organ damage, and possibly death.Ī milliamp (mA) is a unit of measurement for the flow of electrons through an electrical wire. The degree of electrical shock received by a person varies depending on the amperage, duration, and course of electric current in the body when they come into physical contact with an electrical source. The amount of pressure that electrons experience in a circuit is measured in volts, whereas the amount of work generated by moving electrons is measured in watts. 6.24 x 1018 electrons / second is equivalent to one amp.Īmperage is measured in amps, voltage is measured in volts, and wattage is measured in watts. An ampere is a unit of measurement for electrical current in Coulombs per second. It is produced when electrons, which are negatively charged particles, are driven to travel in a single direction across a conductor. ![]() Electrical current is the pace at which an electrical charge flows through a conductor to time. ![]()
