Data Harvest

Current - 1A
Product Description

+/- 1A mid range current sensor for d.c. and low-voltage a.c. measurements. Use in conjunction with voltage sensors to investigate Ohm’s law, power and circuits.

 


28 -sec Change in magnetic field and induced current


1-minute Data Harvest capacitor - charge & discharge

 

Teaching applications:
  • What changes the current in a circuit?
  • Good and bad conductors
  • Can you use bulb brightness to measure current?
  • Ohm’s law
  • Series and parallel circuits
Extension and advanced ideas:
  • Electrical component characteristics e.g. a light dependent resistor
  • Capacitor discharge, charge and energy stored
  • Faraday’s induction in a coil, induction of current in a conductor
  • Power
  • Heat and electric current
  • Avagadro’s number

  • Offset removed by Tare function in software.
  • Be aware that some power supplies are ½ wave rectified producing an average rather than true DC. The Current Sensor will ‘pick up’ the fluctuations in voltage and current from this type of power supply.
  • The Current sensor should be placed in series with the circuit component through which the current is measured. Currents in either direction can be measured. The Current sensors have a very low resistance so that they introduce as little resistance as possible to the circuit.
