he current which depends upon the potential of the circuit ispassed through the movable coil or coils. The resultant effect isdue to the product of the fields produced by the two currents; andconsequently, it is directly proportional to the power in watts, inas-much as the power in watts is… … Portable Instruments. Direct Deflection Type. The precision-balance types of electrodynamometer instruments, just described,can be read only on steady loads; consequently their use is largelyrestricted to the laboratory. The direct deflection types of in-struments, since they require noadjustment…
