0mA

0mA refers to zero milliamperes, a unit of electric current. Milliamperes (mA) measure the flow of electrical charge, with one milliampere being equal to one-thousandth of an ampere. Therefore, 0mA signifies no electrical current is flowing in a circuit or through a device. This can be a normal operating state for some components, indicating they are inactive or powered off.

In electronic contexts, a reading of 0mA is often observed when a device is in standby mode, has been disconnected from a power source, or when a circuit breaker has been tripped. It can also be a diagnostic indicator. For instance, a device that is expected to draw current but is instead showing 0mA might suggest a break in the circuit, a faulty power supply, or a malfunctioning component preventing current flow. Troubleshooting often involves checking for expected current draw; a deviation to 0mA when current is anticipated can pinpoint a problem. In safety systems, 0mA might represent a normal, unactivated state, with current flow only occurring during an alarm or operational event.
