Question

Where does the current come from that moves the needle on an analog volt meter?

a) The voltage source being measured
b) The operator's hand
c) The magnet inside the meter
d) The battery inside the meter

Answer 1

The current that moves the needle on an analog volt meter comes from the voltage source being measured.

Step-by-step explanation:

The current that moves the needle on an analog volt meter comes from the voltage source being measured. In an analog meter, the heart of the meter is a device called a galvanometer, which is essentially a coil of wire with a small resistance in a magnetic field. When current flows through the coil, it produces a proportional needle deflection due to the force of the magnetic field upon the current-carrying wire.
