A unit for measuring the electrical current in complex (including coaxial) circuit sections
A simple unit for measuring electrical current in complex (including coaxial) circuit sections is considered. A conductor
section of the basic measured circuit, to which a light-emitting diode, a galvanic cell, and a regulating resistor are connected,
is used as a shunt. A signal from the light-emitting diode arrives at the measuring system. The unit is intended for measuring
both large (kilo- and megaampere) and relatively small (up to several amperes) values of the direct, alternating, and pulsed
current.
