Question

When does the ammeter reading decrease and increase? ​

Answer 1

your answer

The ammeter gives the value of current flowing in the whole circuit since the components are connected in series. For the current in the circuit (ammeter reading) to decrease, the total resistance in the circuit should increase. The resistance of the fixed resistor on the left cannot be increased.

Answer 2

Answer:

$\huge \mathfrak \pink {Ammeter}$

The ammeter reading decreases to one - half when the length of the wire is doubled. The ammeter reading is increased when a thicker wire of the same material and of the same length is used in the circuit. A change in ammeter reading is observed in a wire of different material of the same length and same area of cross section is used.
