[quote uid=bigDoc pid=811] (3aiv) voltmeter reading E=2.0V tabulate SN:1,2,3,4,5,6 R(ohms):1.00|2.00|3.00|4.00|5.00|6.00 R^-1(ohm ^-1):1.00|0.50|0.33|0.25|0.20|0.17 V(v):1.80|2.10|2.30|2.40|2.50|2.60 V^-1(V^-1):0.56|0.48|0.43|0.42|0.40|0.38 (3aix) slope= ((0.56-0.38)/(1.00-0.17)) =0.18/0.81=0.22 ohm V^-1 intercept on vertical axis 0.35V^-1 (3ax) value of c^-1= c^-1=1/c c^-1=1/0.35 c^-1=2.857 (3axi) (i)I ensured that the connecting wires are tightly connected (ii)i avoided error due to parallax when taking the voltmeter by ensuring i viewed the scale directly in front of it (3b) Electromotive force(E.M>F) is more than the terminal pd when current is supplied from external resistance which drop the e.m.f of the cell [/quote]
