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.
What do you mean balance condition of a bridge circuit?
The balance condition of a bridge circuit, such as a Wheatstone bridge, occurs when the ratio of resistances in one arm of the bridge is equal to the ratio in the other arm, resulting in zero voltage across the bridge's output terminals. This condition allows for precise measurements of unknown resistances by comparing them to known values. When balanced, the circuit is in equilibrium, and no current flows through the galvanometer connected across the bridge. Achieving this balance is crucial for accurate sensor readings and measurements in various applications.
What is dc briges?
A DC bridge is an electrical circuit used to measure unknown resistances by balancing two legs of a circuit. The most common type is the Wheatstone Bridge, which consists of four resistors arranged in a diamond shape, with a galvanometer to detect the balance. When the bridge is balanced, the ratio of the known resistances can be used to calculate the unknown resistance. DC bridges are widely used in laboratory settings for precise measurements.
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 Wheatstone Bridge is used to measure resistance of an electrical / electronic component. The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter! It uses a completely-different method of measuring resistance and is significantly more accurate than a multimeter. The purpose of the very sensitive galvanometer is to detect when the Bridge circuit is 'balanced', by sensing the current (not voltage!) passing through it. When no current flows, the Bridge is balanced.
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 can you connect a galvanometer to a curcuit?
To connect a galvanometer to a circuit, first, ensure the galvanometer is rated for the voltage and current levels of your circuit. Connect the positive terminal of the galvanometer to the positive side of the circuit and the negative terminal to the negative side. Optionally, include a resistor in series to limit the current and protect the galvanometer from damage. Finally, ensure all connections are secure to maintain accurate readings.

Why galvanometer show one side deflection in meter bridge experiment?
Well, honey, a galvanometer shows one-sided deflection in a meter bridge experiment because the galvanometer is connected in series with the unknown resistance being measured. The current flows through the galvanometer in one direction only, causing it to deflect to one side. It's just the way the cookie crumbles in the world of electrical measurements, sugar.
How do you locate fault using whetstone bridge?
To locate a fault using a Wheatstone bridge, you first connect the bridge to the circuit where the fault is suspected. By adjusting the bridge until it is balanced (indicating zero voltage difference across the galvanometer), you can determine the resistance values in the circuit. If the bridge remains unbalanced, the difference in resistance can help identify the location of the fault by comparing with known resistance values. The point where the fault occurs can often be inferred from the changes in resistance readings throughout the circuit.

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.
