Case: Read the passage and answer the following questions

Kirchhoff's first law applies to currents at a junction in a circuit. It states that at a junction in an electrical circuit, the sum of currents flowing into the junction is equal to the sum of currents flowing out of the junction. Kirchhoff's second law, also known as Kirchhoff's voltage law states that the sum of all voltages around a closed loop in any circuit must be equal to zero. This again is a consequence of charge conservation and also conservation of energy. Wheatstone bridge, also known as the resistance bridge, calculates the unknown resistance by balancing two legs of the bridge circuit working on Kirchhoff's law.

Why is the Wheatstone bridge better than the other method of measuring resistance?

It is a null method

A Wheatstone's bridge is more accurate than the other methods of measuring resistance because the resistance is obtained using the null method. In the null method, the resistance of the galvanometer and the internal resistance of the cell does not affect the null point.
