Does interchanging the galvanometer ad battery in a wheatstone bridge affect the balance?
No.AnswerWork it out, yourself, from first principles. Start with the assumption that, for the bridge to be 'balanced' (i.e. with no current flowing through the galvanometer), the potential-difference across the galvanometer is zero. It is quite simple.
Why is one need to turn off the circuit in between measurement when using the wheatstone bridge?
Removing the resistor that you are measuring while the circuit is still on, would create an excessive amount of current to flow through the galvanometer, possibly damaging it.
Why doesn't any current flow through the galvanometer in a balanced Wheatstone bridge?
There is no current flow through the galvanometer in a balanced Wheatstone bridge because, in the balanced state, the voltage on both terminals of the galvanometer is the same. Since the voltage differential in zero, there can be no current.
Why a wheatstone circuit is called a bridge?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
Working of moving-coil galvanometer?
A moving coil galvanometer is a type of scanning device used in the transportation and trucking industry. The vehicle is pulled through a fixed scanner while an operator watches a closed circuit television.
In a balanced condition of a bridge circuit a bulb was placed instead of galvanometer will the bulb light up?
No, It will go out.
Why galvanometer is connected in wheatstone bridge?
A galvanometer is connected in a Wheatstone bridge circuit to detect any imbalance or difference in resistance between the two arms of the bridge. When the bridge is balanced, there is no current flowing through the galvanometer, indicating equilibrium. Any deviation from balance causes a current to flow through the galvanometer, allowing the user to make adjustments to achieve balance.
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.
How do you troubleshoot galvanometer?
with a wheatstone bridge

Which circumstances would a current register on the galvanometer?
A current would register on a galvanometer when there is a flow of electric charge through the circuit that the galvanometer is connected to. The galvanometer measures the strength and direction of the current passing through it, displaying this information as a deflection on its dial.
What is effect of interchanging the galvanometer and driver cell in meter bridge?
Interchanging the galvanometer and driver cell in a meter bridge would reverse the deflection of the galvanometer. The direction of current through the bridge wire would also change, affecting the balance point. The new balance point will now represent a different ratio of the unknown resistance to the known resistance.
What is the function of galvanometer?
To measure electric current intensity.
Why galvanometer show one side deflection in meter bridge experiment?
there may be two possible errors 1) it may be bcz of the change in the polarities while connecting the circuit 2) the connection may not be tight
Half deflection method to find galvanometer resistance?
We can find it by using wheatstone bridge.
