The current measuring part of the Avometer consists of number of low resistances connected:
Correct answer: B. Parallel with the galvanometer
- A. At an angle of 180° with the galvanometer
- B. Parallel with the galvanometer
- C. At an angle of 45° with the galvanometer
- D. Perpendicular to the galvanometer
Explanation
Explanation:The current measuring part of an ammeter consists of a low resistance connected in parallel with the galvanometer. This is done so that most of the current passes through the low resistance, while a small part of the current passes through the galvanometer. This option is not correct because the low resistances are connected in parallel with the galvanometer and not an angle of 180°. This option is also incorrect because the low resistances are not connected at an angle of 45° with the galvanometer. This option is also incorrect because the low resistances are not connected perpendicular to the galvanometer.

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.
