Introduction
♦ Current sensor is used to measure the current in circuit. When current passes through resistor, it will form a tiny electric potential difference at both ends of the resistance. After circuit amplifying, it can accurately measure the current in DC circuit or low-voltage, low-frequency AC circuit.
Usage
♦ Connect Current Sensor to any port in SenseDisc.
♦ Connect red and black alligator clips to positive and negative poles in Current Sensor.
♦ Series connect Current Sensor into circuit.
Notes
♦ Current sensor should be series connected to circuit.
♦ Current sensor needs to be calibrated before using.
♦ The maximum current can be applied to sensor is 3A.
Typical experiment
Typical experiment
♦ Ohm's Law
Others
♦ Series and parallel connection of resistor
♦ Measure the VA characteristic curve of small bulb
♦ Measure the electrodynamic potential and internal resistance of battery
