Example 7: The experiments set-up given below measures the value of unknown resistance in two steps. Switch 2 R G • When V=24 V, r is set at 400 52 and 5=8052, galvanom- eter shows a deflection of 30°. The value of unknown resistance Ris (Λ) 80 Ω (C) 40 S • When switch is thrown to position 2 the supply voltage drops down to 22 V and the galvanometer still shows a deflection of 30°. (B) 60 (D) None of the above
