Digital Signal Processing and Artificial Intelligence for Automatic Learning Nikola Draganov 2 1 2023 https://doi.org/10.6025/dspaial/2023/2/1/21-26 https://www.dline.info/dspai/fulltext/v2n1/dspaiv2n1_3.pdf Electrical current is a diverse electrical quantity. The measurement systems have many direct methods for measurement. We have used an indirect contactless model for measuring the magnetic field by developing a flow through a conductor electrical current. We found that the contactless measurements have high sensitivity and wide frequency with high reliability. They have better linear characteristics due to the parallel bridge resistors.
