An ammeter and a voltmeter are connected in series to a battery with emf E = 6 volt and negligible resistance.
When a resistance R 3Ω is connected in parallel to voltmeter, reading of ammeter increases three times while
that of voltmeter reduces to one third.
41. The resistance of ammeter is :
(A) 24 Ω (B) 8 Ω (C) 4 Ω (D) 3 Ω
42. The resistance of voltmeter is :
(A) 24 Ω (B) 8 Ω (C) 4 Ω (D) 3 Ω
