A) 200
B) 100
C) 10
D) 50
Correct Answer: B
Solution :
Since voltmeter records 5V, it means the equivalent. Resistance of voltmeter and 100 W must be 50, because in series grouping if resistances are equal, they share equal potential difference. It conclude that resistance of voltmeter must be 100W.You need to login to perform this action.
