Question

Which of the following is NOT a characteristic of a balanced Wheatstone bridge?

Options

• Non-zero potential difference across the galvanometer

• Zero galvanometer current

• Applicability of the balance formula

• Accurate resistance measurement capability

Answer 1

In a balanced Wheatstone bridge, the potential difference across the galvanometer is zero, not non-zero. The balance condition creates equal potentials at the galvanometer junctions, resulting in zero current flow and enabling accurate resistance measurement using the balance formula.
