The Wireless Current Sensor's wide current range enables introductory and advanced explorations of electricity and basic circuits. Designed with user safety in mind, the sensor can be used to measure currents up to 1 A and includes built-in overload protection. Collected data can be wirelessly transmitted to computers, Chromebooks, tablets, and smart phones. When combined with a Wireless Voltage Sensor, students can explore Ohm's Law, series and parallel circuits, and much more.
Since current can only exist in a complete circuit, the Wireless Current Sensor must be part of that circuit to measure current. It is connected in series and has a very low resistance (0.1 Ω). For this reason, we do not recommend connecting it directly across a battery or other voltage source without a resistive load.
Current sensors in chemistry enable students to count electrons involved in driving reactions much like a scale accounts for mass in reactions. Amperage determines how many atoms are involved in a chemical reaction. Since the two are related, current can be used to find out how much reactant is available in solution. Integrating currents keeps track of how much metal might electroplate onto an electrode.
