It does respond, but not in an useful way. A galvanometeris a d.c. instrument. If supplied with a.c., the resulting torque on the instrument's pointer will attempt to change direction in line with the changing polarity of the alternating current. Because the frequency is relatively high (50/60 Hz), the pointer will simply vibrate. However, if the frequency was low enough, and the galvanometer had a centre zero scale, then the pointer would sweep back and forth in line with that voltage.
What else can I help you with?
Does the galvanometer measures AC and DC current?
It is used to detect very small DC currents only. For AC signals Detectors are used.
Can moving coil galvanometer be used to detect ac in a circuit give reason?
Moving coil galvanometer is used to detect unknown resitance of the both ac or dc circuits :)deepak instrumentation engineerAnswerA 'galvanometer' is simply an instrument that detects and measures small currents; 'moving coil' describes its operating principle. A moving-coil galvanometer is a d.c. instrument; if subject to a.c., then it will simply vibrate as it will not be able to respond the the frequency (unless the frequency is very low, in which case, it will sweep back and forth in step with that frequency).The moving-coil principle is applied to other instruments, and can be used in the construction of multimeters. In the case of a multimeter, a rectifier circuit is incorporated so that it can be used to measure a.c. currents and voltages.
Is galvanometer generator alternating current or direct current needed to operate an electric motor?
That depends if it is an ac or dc motor.
What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Do galvanometer has positive or negative terminals?
Absolutely not. The reason behind is that it shows currents (both ac and dc) which has a desired direction of flow of electrons.. So Galvanometer does not have any electrolytic terminals!!

Is galvanometer used in ac circuits if not why?
firstly a galvanometer instrument measures very small amounts of current flow of a D,C, nature / type . an a.c. type circuit is likely to be of a high magnitude , such that it would render the instrument unusable and dangerous to the operator . also a galvanometer by design is known as a moving coil type meter , if an ac signal were to be connected to this, the rate of change of the ac signal voltage would be so fast / frequent that the user would be unaware that the signal is currently changing

That depends if it is an ac or dc motor.

Why DC ammeter or voltmeter is not used in AC circuits?
Short answer, because it is designed for DC, not AC.In AC, the current goes back and forth all the time; the average current is zero. And that's what a galvanometer that is not especially designed for AC would show.
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
How far can the loop in a galvanometer travel?
The loop in a galvanometer can typically travel within a limited range, usually between ±90 to ±180 degrees, depending on the design of the instrument. This range allows the coil to respond to varying currents and produce a proportional deflection on the dial.
When you get a text how do you respond to lol?
You cant. sorry. :/
How can you fix an ac leak in your car?
You cant
