[quote uid=bigDoc pid=810] (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]
