Answer 1

Ur ans is 75V

Bcause no current will Pass through the last two conductors

Cuurent goes through waire so no potential drop will be their

Answer 2

Two resistors of 10 ohms are shorted

so effective resistance of that part will  be negligible

so resistance of circuit

= 10Ω + 10Ω

= 20Ω

Current = 100/20 = 5A

Voltage across resistance where voltmeter is place = 5 * 10 = 50V

option 2 - 50 V is correct
