Questions
As shown in circuit diagram an ideal voltmeter and an ideal ammeter reading are zero. Sum of potential drop across box and 5 Ω resistances will be (given that there are no fault in voltmeter and ammeter)
detailed solution
Correct option is C
Since voltmeter is ideal reading of voltmeter is zero.So, either fault is in box or 5 Ω resistance.So, potential difference across box and 5 Ω resistance will be 12 voltTalk to our academic expert!
