What happens when a shunt resistor is connected with galvanometer?

A shunt resistance is connected in parallel to the galvanometer so as to keep the resistance low. Such low resistance galvanometer is used in series with the circuit to measure the strength of current through the circuit.

What is the effect of shunting a galvanometer?

Since the Shunt bypasses part of the current, the result is reduction in sensitivity. The lower the resistance of the shunt the lesser the sensitivity of galvanometer and vice-versa the higher the resistance of the shunt the higher the sensitivity of the galvanometer.

What is effect of shunt on current sensitivity?

If you want to measure higher current then you can connect a shunt resistor in parallel with the meter and have the two in series with the rest of the circuit. The two together (internal and shunt) will assure that a current smaller than the meter’s limit will flow through it.

When galvanometer is converted into ammeter the resistance connected is?

A galvanometer is converted into an ammeter when we connect a low resistance in parallel. 2. A galvanometer is converted into a voltmeter when we connect a high resistance in series.

How shunt is connected with the ammeter?

The shunt connects in parallel to the ammeter because of which the voltage drops across the meter and shunt remain the same. Thus, the movement of the pointer is not affected by the shunt.

What is the relation between the sensitivity and deflection for a galvanometer?

What is the relation between the sensitivity and deflection for a galvanometer? Thus we see that sensitivity is directly proportional to the deflection. Sv = θ⁄e. So the unit of voltage sensitivity is degrees per volts as deflection is measured in degrees and voltage is in volts.

What is the relation between the sensitivity and deflection for A galvanometer?

How shunt decreases the sensitivity of galvanometer?

What happens when galvanometer is connected in series?

The galvanometer is converted into the ammeter by connecting the resistance in parallel with the circuit. And if the resistance is connected in series with a galvanometer, then it is used as a voltmeter. It is connected in series with the circuit for determining the exact value of circuit current.

How do you convert a galvanometer into an ammeter Why is an ammeter always connected to the circuit in series?

So ammeter is connected in series to measure the circuit current. A galvanometer is converted into an ammeter by connecting a low resistance in parallel with the galvanometer. This low resistance is called shunt resistance S. Since, the deflection in the galvanometer is proportional to the current passing through it.

How will you convert a galvanometer into an ammeter What is the effective resistance of ammeter?

A galvanometer can be converted into ammeter by connecting a low resistance called shunt in parallel to the galvanometer. Since S is low resistance, resistance of ammeter RA is very low and when it is connected in series in the circuits, it will not affect the current passing through the circuit.
