With a high resistance in the outside circuit, the deflections of the
ammeter will be small, but such as they are, they will fairly
accurately represent the electromotive forces which produce them.


Voltmeters (Fig. 236), or instruments for measuring voltage, are like
ammeters except that a wire of very high resistance is in circuit with
the movable coil. In external appearance they are not distinguishable
from ammeters.
