Assertion (A) : Higher the range, lower is the resistance of an ammeter.

Reason (R) : To increase the range of an ammeter additional shunt is added in series to it.

Case Study :

An experiment was set up with the circuit diagram shown in figure. Given that R₁ = 10 $$\Omega$$, R₂ = R₃ = 5 $$\Omega$$, r = 0 $$\Omega$$ and E = 5 V

The points with the same potential are -
