False Statement: Wheatstone bridge is susceptible to high DC.
Explanation:
Wheatstone bridge is a circuit used to measure unknown resistance by comparing it with a known resistance. It consists of four resistors arranged in a diamond shape with a galvanometer connected between two junctions. When the bridge is balanced, the galvanometer shows no deflection, indicating that the ratio of resistances is equal.
Advantages of Wheatstone Bridge:
1. High Precision: Wheatstone bridge is widely used for precision measurement due to its high accuracy. It can be used to measure resistances with high precision and is not affected by temperature variations.
2. High Sensitivity: It can detect small changes in resistance and is commonly used in applications where precise measurements are required, such as strain gauge measurements.
3. Low Error: When the bridge is balanced, the error introduced by the contact resistance is minimized. This error is negligible in comparison to the precision of the measurement.
4. Wide Range of Applications: Wheatstone bridge can be used to measure various physical quantities such as resistance, capacitance, inductance, and even temperature.
False Statement Explanation:
The false statement in the given options is that "Wheatstone bridge is susceptible to high DC." This statement is incorrect because Wheatstone bridge is not affected by the presence of DC voltage. It can still accurately measure resistances even in the presence of a DC voltage. However, it is important to note that the bridge is designed to operate with low voltages to avoid excessive power dissipation and potential damage to the circuit components.
Conclusion:
In conclusion, the false statement is that Wheatstone bridge is susceptible to high DC. The Wheatstone bridge is a highly accurate and precise circuit that is commonly used for precision measurements. It is not affected by the presence of DC voltage and can be used for a wide range of applications.
