Introduction

The PASCO CI-6556 Current Sensor is designed to be

used with a PASCO computer interface to measure

currents of ±1.5 amperes.

The Current Sensor can be plugged directly into any

analog channel (A,B, or C) on the PASCO 700i Science

Workshop interface or analog channel A on the 300i or

500i Science Workshop interface. This is because the

Current Sensor should only be connected to a non-ground

referenced, differential input.

Current passing through the two input connectors

develops a voltage across the 1.00 Ω, 2 W resistor in the

Current Sensor. The voltage developed at the resistor is

related to the current according to Ohm's Law:

V = I x R

(where V = voltage in volts, I = current in amps, and R =

resistance in ohms).

Since the Current Sensor utilizes a 1.00 Ω resistor, the

voltage seen across the resistor is equal to the current

flowing through the resistor. The computer interface

channels this voltage into Science Workshop, which

reports the value in amperes (A) of current.
