1130 - Wireless 20V Voltage & Current Sensor
11 / 19 | Revision: 1.0 | DS157
Practical Investigations
The Smart Wireless 20V Voltage & Current Sensor can be used wherever you would use a voltmeter or
ammeter. The advantage of using these sensors over multimeters will be the ability to use many
sensors, record the data via software, and record fast transient events. Examples of practical work
where use of the sensor will enhance learning and understanding include work to study:
·
What changes the current in a circuit?
·
Series and parallel circuits
·
Ohm’s law
·
Good and bad conductors
·
Alternative power investigations e.g. solar cells, water power, wind energy, etc
·
Fuses
·
Laws of resistance
·
Long wires, less power?
·
Electrical component characteristics
·
Dynamo effect
·
Start-up current of a lamp
·
Faraday’s induction of current or voltage in a coil
·
Capacitor discharge, charge and energy stored
·
Diodes: a.c.. diode rectification
·
Specific heat capacity for a liquid or solid
·
Calibration of a thermometer
·
Impedance change with frequency
·
Efficiency of an electric motor / generator
·
Resonance in a series LCR circuit
·
Reactance and phase in a capacitor
With the software set to a numeric display the sensor and software will create a digital voltmeter and
ammeter.
