FAQ's

What is a current loop calibrator?

Current loop calibrators are specially designed instruments for current loop trouble shooting, testing and calibration. They can source current on unpowered devices in a loop, simulate the operation of loop powered transmitters and also measure current. These calibrators often feature time saving technology, specialist graphics using digital interfaces and micro-processor based electronics.

How much current flows in each loop of a parallel circuit?

Determined by Ohm's law, which states that the current between 2 points through a conductor is directly proportionate to the voltage across those 2 points, divided by the resistance of the conductor. I = V/R. This is also the case for series and parallel circuits, however in parallel circuits the total current can be affected by the way the resistors have been connected, as well as their ohmic value. Current does divide up and there can be more current in one area over another nonetheless when all areas are added up the total amount is the same.
