Voltage sensor
Wireless voltage sensor for a digital laboratory: Ohm's law, source emf and capacitor circuit in six activities.
The wireless sensor measures the voltage in sections of the electrical circuit and transmits the data to a digital laboratory system. It supports six experiments: checking Ohm's law, voltage distribution in a series connection and Kirchhoff's second law, determining the emf and internal resistance of the current source, studying the voltage on a capacitor during charge and discharge, studying a voltage divider and potentiometer, measuring voltage drops in a branched circuit. The sensor is designed for laboratory activities and demonstrations on electrodynamics in a physics course.
- Testing Ohm’s law: proportionality between the voltage across a resistor and the current through it
- Voltage distribution across components connected in series (Kirchhoff’s second law)
- Determination of EMF and internal resistance of a current source
- Study of the voltage on a capacitor during its charge and discharge
- Studying the operation of a voltage divider and potentiometer
- Measuring voltage drop across individual sections of a branched circuit
