Then the total resistance of the circuit would be dominated by RL. Using Ohm''s law, we can calculate the current through the circuit as $$ I = frac{V_o}{R_s+R_L} $$ Since Rs is much smaller than RL, we can say $$ I = frac{V_o}{R_L} $$ This means that the battery can supply any current that RL allows, as long as RL is much larger than Rs.
