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.
Modern electronic multimeter measures resistances by?
forcing a constant current and measuring the voltage across the unknown resistor.
How can you convert galvanometer into ammeter?
Since Galvanometer is a very sensitive instrument therefore it can't measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.
Can moving coil galvanometer be used to detect an alternating current in a circuit?
no. it,s only used to measure D.C
Principle of multimeter?
Based on the principle of the D'Arsonval galvanometer, the main function of a multimeter is measuring a circuit's voltage, current, and resistance.
What is the unit measured in with a galvanometer?
It measures current.
What instrument measures current flowing through wires in a house?
galvanometer
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 does galvanometer measures?
Electrical current. Invented by the Italian physiologist, Luigi Galvani.
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.
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..
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
Name the instrument used to measure electric current?
A magnetic compass can detect current, butyou'll need an Ammeter to measure it.A galvanometer can detect current ~ butyou'll need an Ammeter to measure it.
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 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.
Does the galvanometer measures AC and DC current?
It is used to detect very small DC currents only. For AC signals Detectors are used.
