Ampere turns is the unit of Magneto Motive Force of a magnetic circuit, the equivalent of emf in electrical circuit. The MMF is measured as the product of the dc current flowing through the circuit and the number of turns. The higher the number of turns in a coil, higher will be the magnetomotive force for the same current.
However, this relationship holds true only till the core of the coil gets saturated, after which there is no change in mmf for an increase in current.
The field strength of a coil is the magnetomotive force per unit length. This is measured as ampere-turns per metre.
Current Limiting Fuses
Current limiting fuses are used in systems where high fault levels can result in excessive fault currents. The fuses function
as normal fuses; however, they are designed to limit the fault current to low levels when they operate.
During normal operation, the fuse has a low resistance. Read More
