Voltage, current and power – our Voltage/Current Sensor measures them all simultaneously, either on a digital display or graphed over time. Overload protection shuts down the sensor (and gives an audible beep to alert the teacher) when the current is too high. Sensor automatically resets after the overload is removed. No smoke, no blown fuses to replace.

• No grounding problems - differential input lets your students measure voltage or current anywhere in the circuit, no need to worry about which point is or is not at ground.
• Full ±10V and ±1A range. Works with a wide variety of configurations of battery electronics and circuits.

Typical Applications

• Measure capacitor charge/discharge
• Study the relationship of voltage and current in series-parallel circuits (Ohm's Law)
• Measure power used by an electrical device (P= VI)
