Answer / kotresh marali

in the limit R--->0, v1--->v this becomes ideal voltage
source... the graph for will be like ,
take i1 in x axis and v1 in y axis... such that as and when
current increases the voltage should remain constant(v)...

Answer / gunjan kumar

the main characteristics of ideal voltage source is that the load voltage must be independent of load drawn.for this source resistance should be zero
