A galvanometer is like a small DC motor with a spring to stop it from rotating all the way around. The greater the voltage the stronger = further the "motor" pulls the needle.

What is the principle of ballistic galvanometer?
when current passes through a coil of b.g then it rotates in a magnetic field and measures the quantity of charge rather than current
What does galvanometer measures?
Electrical current. Invented by the Italian physiologist, Luigi Galvani.
Difference between galvanometer and voltmeter?
Galvanometer is similiar to ammeter which is used to detect small current through it whereas a voltmeter measures the potential difference in a cicuit..
What measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
a galvanometer.
What is Ballistic galvanometer Explain its construction?
A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.
What is the unit measured in with a galvanometer?
It measures current.
Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
What is the principle of ballistic galvanometer?
when current passes through a coil of b.g then it rotates in a magnetic field and measures the quantity of charge rather than current
How do you convert galvanometer to ohmmeter?
Ohms are the unit of measurement for resistance, so an ohmmeter is a device that measures electrical resistance. A galvanometer measures the current flowing through the resistance, so the two are related. To convert a galvanometer into an ohmmeter, one needs an external battery.
What instrument measures current flowing through wires in a house?
galvanometer
What instrument measures small currents?
A galvanometer is used to measure small currents.
What does galvanometer measures?
Electrical current. Invented by the Italian physiologist, Luigi Galvani.
Difference between galvanometer and voltmeter?
Galvanometer is similiar to ammeter which is used to detect small current through it whereas a voltmeter measures the potential difference in a cicuit..
What quantity measures the galvonometer?
A galvanometer is a type of ammeter: An instrument for detecting and measuring electric current.
What measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
a galvanometer.
What is one different between a galvanometer and an electric motor?
Electric motor is a machine that converts electrical energy to mechanical energy while a Galvanometer is an electrical instrument that measures small values of current.
What is ballistic galvanometer.Give the construction and theory of moving coil ballistic galvanometer.?
a ballistic galvanometer is a specially designed galvanometer suitable for measuring the total quantity of electricity or charge displaced by a varying current of short duration such as charging & discharging of a capacitor >>>>
