er circuit is set up as shown The potential gradient across the potentiometer wire is k volt cm and the ammeter present in the circuit reads 1 0 A when two way key is switched off The balance points when the key between the terminals i 1 and 2 ii 1 and 3 is plugged in are found to be at lengths cm and cm respectively The magnitudes of the resistors R and X in ohms are then equal respectively to 1 W LO A 1 ke and kl R 3 X B G 2 k l and kl
