357407 A \(d.c\) main supply of e.m.f. 220 \(V\) is connected across a storage battery of e.m.f. 200 \(V\) through a resistance of \(1\Omega \). The battery terminals are connected to an external resistance \(‘R’\). The minimum value of \(‘R’\), so that a current passes through the battery to charge it is :-
