Claim 28:
29. A current measuring resistor for measuring an electric current, comprising:
a) a first connection part comprising a conductor material for introducing the electric current into the current measuring resistor,
b) a second connection part comprising a conductor material for conducting the electric current out of the current measuring resistor, and
c) a resistor element comprising a low-resistance resistance material, the resistor element being arranged in a direction of current flow between the first connection part and the second connection part and being joined to the first and second connection parts so that the electric current to be measured flows through the resistor element during operation and produces a voltage drop across the resistor element,
d) wherein the first connection part, the second connection part and the resistor element each have a substantially round cross-section in a sectional plane at right angles to the direction of flow of the electric current and, wherein a photocell is integrated into the current measuring resistor for a sole or supporting power supply.
