Measuring current is one of the basic requirements in many electronic systems; whether for precise control or simple protection of circuit elements. A family of new devices has been produced to greatly simplify the measurement of DC or AC current. Using only external resistors, each small device can be tailored to specific needs and used in a wide range of operating conditions.
This video will show basic, precision, bi-directional and high voltage circuits for measuring current. In each example, the difficult task of measuring a current on a high voltage rail is shown.
