The ammeter (assumed ideal) reads 0.48 A. The internal resistance of the battery is (a) 1.0 CI (ft) 0.5 Ap1 (c) 1.5 Api (d) 2 Q. [MANIPAL 1997] 354. A wire 3.00 m long, of uniform cross-sectional area 2.00 mm2, has a conductance of 1.25 S. What is the resistivity of the material of the wire ? [1 S = 1 ... 5 rows of 10 identical cells, connected in series, send a current I through an external resistance of 20 ohm.
