Current - 10A   Home / SmartQ Sensors  

+/- 10A high 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. This high range sensor is very good for measuring start up current in incandescent, filament lamps and for studying fuses. For smaller currents use the 100 mA or 1A sensors.

This high range sensor is very good for measuring start up current in incandescent, filament lamps and for studying fuses.

current with vision and circuit in meters mode
Teaching applications:
  • What changes the current in a circuit e.g. when using light bulbs?
  • Good and bad conductors
  • Can you use bulb brightness to measure current?
  • Ohm’s law
  • Series and parallel circuits
  • Start up current of a lamp
 

Lascells circuit setup
Extension and advanced ideas:
  • Electrical component characteristics e.g. a light dependent resistor
  • Capacitor discharge, charge and energy stored
  • Power
  • Heat and electric current
  • Avagadro’s number
  • Effect of current on Electromagnet strength Specific Heat Capacity for a liquid or solid
  • 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.
