Current probe

Current probe
When it comes to measuring alternating currents in a safe manner, crrent probes have a number of signtficant advantages over series resistors. To begin with, the measuring circuit is electrically isolated from the a.c. supply line which carries the current to be measured. Secondly, the a.c. supply Iine need not be broken to insert a series resistor, or a cluster of series resistors with an associated range switch. Thirdly, voltage loss caused by the the current probe is negligible.
