A galvanometer basically is an instrument used to ____________________?
Correct answer: A. detect current in a circuit
- A. detect current in a circuit
- B. measure current flowing through a circuit
- C. measure voltage across a circuit
- D. measure potential difference between two points in a circuit
Explanation
A galvanometer is a sensitive instrument used to detect the presence and direction of a small current by the deflection of its coil. Students often choose b because a galvanometer can be calibrated to measure current, but its basic purpose is detection rather than accurate current measurement.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
