12.11 Electrical Instruments
A galvanometer detects the presence of current in the branch where it is connected.
It is the basic instrument used in making various meters, such
(i) ammeter (measures current)
(ii) voltmeter (measures voltage or potential difference)
(iii) ohmeters (measures resistance)
(iv) powermeter (measures power)
A galvanometer can detect a current as low as 10–9 A.
In DC circuits, usually moving coil type galvanometers are used. Its deflection is directly proportional to the current that passes through it, or
I µ q or I = Kq
where K is called galvanometer constant.
