Description
The Wireless Voltage Sensor is ideal for exploring the fundamental concepts of electricity, voltage, and basic circuits. It measures voltages up to ±15 V with built-in overload protection and features high-speed sampling rates when used with a USB. When combined with the Wireless Current Sensor, students can use it to explore Ohm’s Law, circuits in series and parallel, and much more.
In Chemistry, the sensor helps students investigate redox reactions, electrolytic cells potentials, and impact of strength of solution on these generated potentials. By testing potential differences between two half reactions, separated by a salt bridge, students can begin to understand the driving forces behind modern batteries.
