Is Galvanometer a Resistor?

The galvanometer also has an internal resistance. If the resistance is known, the galvanometer can be used to measure voltage by utilizing Ohm's law. The full-scale voltage is found by multiplying the full-scale current by the meter resistance.

Does galvanometer have variable resistance?

It is shown that the correct value is the geometric mean of the results of the two methods, if the initial deflections are the same in the two cases; also, the galvanometer resistance equals that value of the variable resistance in the two methods which gives the same second deflection.

What is galvanometer in circuit?

A galvanometer is an instrument that can detect and measure small amounts of current in an electrical circuit. ... This action allows current from the Battery to flow through the circuit (from positive to negative), through the coil positioned between the opposing poles of two Bar Magnets.
