A Wheatstone bridge is in a balanced condition, if galvanometer is short-circuited, the value of currents in various resistors will:
- Increase
- Decrease
- Remain same as before
- Incomplete information
Correct answer: 3. Remain same as before
Explanation: In case of a balanced Wheatstone bridge there is no current passing through the branch containing galvanometer. In such case if the branch containing the galvanometer is short-circuited or open-circuited there will be no change in currents or voltages anywhere in circuit.
