Currents sensors measure both AC and DC, and with differential inputs these sensors can be used anywhere within a circuit and in conjunction with a Voltage sensor.

Applications

Physics:

• Serial and parallel circuits
• Ohm's Law. Resistance in a circuit
• Electrical induction
• Battery life
• Capacitor Discharge and Recharge
• Current surge
• Solar cells
• Electrical component characteristics
• Voltage and Current relationships.

Chemistry:

• Electrolysis

The Current sensor should be placed in series with the circuit component through which the current is measured. 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.
