In a multi range ammeter as the range increases _____________________?
Correct answer: A. shunt value decreases
- A. shunt value decreases
- B. shunt value increases
- C. shunt value remains the same
- D. none of the above
Explanation
For a higher ammeter range, more current must bypass the galvanometer, so a smaller shunt resistance is connected in parallel. The likely wrong choice is b, because students may think a higher range requires a larger resistance, overlooking that the shunt carries the excess current.

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.
