An energy soruce will supply a constant current into the laod, if its internal resistance is

A low voltage supply from which one needs high currents must have very low internal resistance. Why ?

A low voltage supply from which one needs high currents must have very low internal resistance. Why?

If 8 cells having an emf of 1.5 V are connected in series across a load having resistance of 10 Omega . What is the current drawn by the load ? Assume internal resistance of all be 0.5 Omega .

A cell to emf. E and internal resistance r supplies currents for the same time t through external resistance R_1 and R_2 respectively. If the heat produced in both cases is the same, then the internal resistance is given by :
