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.
What is Wheatstone's bridge?
The wheatstone bridge is an instrument used to measure electrical resistance by means of balancing a bridge circuit. The bridge circuit contains two legs, one of which contains the unknown resistance. Variations in wheatstone bridge can be employed to measure inductance, capacitance, and impedance also.

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.
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 The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter!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.
What happens when unknown resistance is changed to other armin wheatstone bridge?
Changing the unknown resistance in a Wheatstone bridge will result in an imbalance in the circuit, causing a potential difference across the bridge. This potential difference can be used to determine the new value of the unknown resistance by adjusting other known resistances until the bridge is balanced again.
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.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
Why using wheatstone bridge in transducer?
You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.
Why is it important to place a potentiometer in the wheatstone bridge ohmmeter circuit?
A potentiometer is essential in a Wheatstone bridge ohmmeter circuit because it allows for precise adjustment of resistance, enabling accurate balancing of the bridge. This fine-tuning helps eliminate errors due to variations in the bridge's arms or external factors. By ensuring that the bridge is balanced, the potentiometer enhances measurement accuracy, allowing for reliable determination of unknown resistances. Overall, it plays a crucial role in achieving high precision in resistance measurements.
