Ammeter
= Ammeter
An <ammeter> measures <electric current> through a branch of an <electrical circuit>. Connect it in series; its own finite <electrical resistance> changes the measured branch's <electric current> unless that effect is negligible or corrected.<University Physics Volume 2 by Samuel J. Ling and others/10.4 Electrical Measuring Instruments>[Measuring Current with an Ammeter, Figure 10.35 and following paragraph: connection and loading]{ref}
