Q1:In an experiment of veificaion of Ohm's Law,following observations are obtained. Potential Difference V (in volt)=0.5,1.0,1.5,2.0,2.5 Current I(in ampere)=0.2,0.4,0.6,0.8,1.0 Q1a:Draw a V-I graph. Q1b:The potential Difference V when the current I is 0.5A Q1c:The current I when the potential difference V is 0.75V. Q1d:The resistance in circuit. Q2:Two wires of the same material and same length have radii 1mm and 2mm respectively.Compare:a.Their resistances and b.Their specific resistances. Q3:A wire of resistance 3 ohm and length 10 cm is stretched to length 30 cm.Assuming that it has a uniform cross section,what will be its new resistance? Q4:A wire of resistance 9 ohm having length 30 cm is tripled on itself.What is its new resistance?
