Question

A cell, a resistor, a key and an ammeter are arranged as shown in the given circuit diagrams. Based on these diagrams, choose the correct option.

(i)	(ii)	(iii)

Options

• The ammeter will show greater current in the circuit (ii).

• The ammeter will show greater current in the circuit (iii).

• The ammeter will show greater current in the circuit (i).

• The ammeter will show equal flow of current in all three circuits.

Answer 1

The ammeter will show equal flow of current in all three circuits.

Explanation:

All three circuits contain the same components connected in series. Changing the positions of the ammeter, resistor or key does not change the current in a series circuit.
