Currents in either direction can be measured. The Current sensors have a very low resistance so that they introduce as little resistance as possible to the circuit. CAUTION: NEVER connect a Current sensor directly across a battery or power supply, without a resistance component to limit the current to within the range of the sensor. Failure to limit the current will cause permanent damage to the sensor. SAFETY: NEVER use high voltages or household AC.
