question unattempted. To measure the resistance of a resistor, a circuit is assembled from an ideal battery, an ammeter and a voltmeter. The voltmeter is connected in parallel with the resistor and shows IV, and the ammeter is connected to the combination in series and shows IA. After the position of the instruments in the circuit was exchanged, the voltmeter shows 2 V, and the ammeter shows 0.5 A. Find the resistance of the resistor in ohm. (A) 192 (B) 20 (C) 2.59 (D) 4.592 किसी प्रतिरोधक का प्रतिरोध मापने के लिये एक आदर्श बैटरी, एक अमीटर तथा एक वोल्टमीटर की सहायता से
