A cell, a resistor, a key and ammeter are arranged as shown in the circuit diagrams of Figure12.1. The current recorded in the ammeter will be

The Current will be given by: I = V/R

R is the total resistance of the circuits

Since V and R are equal in all the three circuits. So, Current will be same in all the three circuits and in series circuit current is same and only potential difference varies.

The current recorded in the ammeter will be same in all the three circuits.
