94The ammeter shown in figure consists of a 480 Ω coil connected in parallel to a 20 Ω shunt. Find thereading of the ammeter.4.10Ω20 V405350937350(C)A(D) A5073(B) 1A(A)A

Answer»

Total resistance of ammeter will be 19.2 ohm now total resistance in ckt will be 29.2 ohm. Current in circuit is 29.2/20 = 0.6479 = 50/73 A.
